Utilizing ng-bind-html to establish Angular bindings within the HTML code

Question

Utilizing ng-bind-html to establish Angular bindings within the HTML code

My scenario involves hitting a specific route (#/abc) and then making a POST request to the server to render the HTML received as a response. Instead of embedding this logic directly into $routeProvider.when, I came up with my own solution.

This is how I tackled it:

Navigate to the designated route
Load an empty view in the ng-view (utilized elsewhere in the app)
The empty view contains a div with
```
<div ng-bind-html=responseHtml></div>
```
In the controller, execute a $http.post and assign the returned data to
```
$scope.responseHtml = $sce.trustAsHtml(data);
```

While this method works well, I have encountered difficulties setting any bindings within the responseHtml.

You can access the corresponding JSFiddle here: http://jsfiddle.net/prakhar1989/LX26M/2/

Being new to AngularJS development, I am uncertain if my approach is optimal. Any advice or pointers would be greatly appreciated!

Thank you!

The directive takes the HTML and its related scope, then uses $compile to process it.

app.directive("ngCompile", function($compile){
    return {
        scope: {
            "ngCompile": "=",
            "ngCompileScope": "="
        },        
        link: function($scope, $element){                    
            $scope.compile = function(){
                $element.html($scope.ngCompile);  
                $compile($element.contents())($scope.ngCompileScope);
            }            
            $scope.$watch("ngCompile",function(){
               $scope.compile();
            });
        }
    }
});

Alternatively, here's a version without isolated scope:

app.directive('ngCompile', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.ngCompile, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});
