Having trouble retrieving input data from a modal pop up with Angular.js

I am facing an issue with my modal pop up form in Angular.js. I am unable to retrieve the form data using ng-model. Below is the code snippet:

<modal title="Owner Information" visible="showModal">
  <form class="ng-pristine ng-valid" id="frmsignup" name="frmsignup" autocomplete="off">
  <div class="input-group bmargindiv1 col-lg-4 col-md-4 col-sm-4 col-xs-12 plr-15">
        <span class="input-group-addon ndrftextwidth text-left">Status:</span>
            <select class="form-control" name="status" id="status" ng-model="status" required="required">
            <option value="">Select Status</option>
            <option value="1">Active</option>
            <option value="0">Inactive</option>
            </select>
  </div>
<div class="input-group bmargindiv1 col-lg-4 col-md-4 col-sm-4 col-xs-12 plr-15">
        <span class="input-group-addon ndrftextwidth text-left">Comment:</span>
            <textarea rows="5" cols="50" class="form-control" id="comment" name="comment" ng-model="comment" required="required">
            </textarea>
    </div>
  <input type="button" class="btn btn-success" ng-click="updateOwnerData();" id="addProfileData" value="Save" />
</form>
</modal>

Here is a glimpse of my modal pop up:

var dept=angular.module('cab');
dept.controller('ownerviewController',function($scope,$http,$timeout,$state,Upload,$window,DataService){
   $scope.updateOwnerData=function(){
          console.log('data',$scope.status,$scope.comment);
   }
})
dept.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog modal-lg">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ title }}</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

The above script part highlights my problem - I cannot fetch values through $scope from the popup window. My goal is to capture these values via Angular.js Scope.

I struggled to identify the issue with scopes. It appears that values are confined within (allowing you to set the initial value for ng-model), but they do not leak outside. Therefore, I opted for utilizing the controllerAs syntax and adhered to the view model principle:

dept.controller('ownerviewController',function($scope){

    var vm = this; // Introducing the view model

    $scope.openPopUP=function(){
        $scope.showModal = !$scope.showModal;
    }
    $scope.updateOwnerData=function(){
        console.log('data', vm.status, vm.comment); //Displaying data from the view model
    } 
})

The next step would involve defining the view model in your template using the controllerAs syntax and updating ng-model bindings:

<body ng-controller="ownerviewController as vm">
...
   <select class="form-control" name="status" id="status" ng-model="vm.status" required="required">
   ...

Understanding Scopes in Directives

When working with the modal pop-up directive, it's important to note that both transcluded: true and scope: true create their own isolated scopes. However, if you want to access and update inputs from your controller's scope, you'll need to take another approach.

To learn more about this concept, check out the visual explanation provided in this resource.

Effective Communication with Parent Scope

If you need to communicate effectively with your parent's scope from within a directive or transcluded-form, consider the following techniques:

Include an individual scope parameter { status: '=', comment: '=' } in your directive, using two-way binding '=' to pass the parent's scope variables like so:
```
<modal title="Owner Information" visible="showModal" data-status="status", data-comment="comment">
```
Create and integrate a factory or service to manage communication, such as updating data, between the directive (form) and controller

An Innovative Solution Using Inherited Scope

For a practical demonstration of utilizing inherited scopes, take a look at this live example. By leveraging prototypical inheritance from the parent scope (controller), you can seamlessly utilize the model (e.g., status, comment) and execute functions within the transcluded form.
