Issues with the functionality of Angular JS services

Hey everyone, I'm relatively new to AngularJS and running into some issues with services. I've been working on a TO DO app in AngularJS using services but I just can't seem to get it to work correctly. Here is my controller:

.controller("myController", ['$scope','toDoService', function($scope,toDoService){

    var lists = toDoService.getLists();
    $scope.lists = lists;

    $scope.add = function(){
      // Any suggestions on what should be added here?

    }

And this is my service:

.service('toDoService', function(){
      this.getLists =function(){
          var list = [
              {"name" : "abebe" ,"done":false, id: Date.now()}
          ];
          return list;
      }


      this.add = function(){
         $scope.lists.push({'name':$scope.nameSpace,'done':false, id: Date.now()});
      $scope.nameSpace = '';
         return this;
      }

  });

Thank you all in advance!

Avoid using $scope within a service. Refer to the example in this Fiddle for guidance on proper implementation.

myApp.service('toDoService', function(){
            this.details = {
        lists: [
              {"name" : "abebe" ,"done":false, id: Date.now()}
          ]
      }
      this.getLists =function(){
          var list = [
              {"name" : "abebe" ,"done":false, id: Date.now()}
          ];
          return list;
      }
      this.addList = function(item) {
        this.details.lists.push(item)
      }
  });

myApp.controller("myController", ['$scope','toDoService',       
    function($scope,toDoService){
    $scope.lists = function() { return toDoService.details.lists };
    $scope.add = function(){
      // WHAT TO PUT HERE????
      var newListItem = {"name" : "abebe" ,"done":false, id: Date.now()}
      toDoService.addList(newListItem)
    }
}]);

Here is the full code snippet:

.controller("myController", ['$scope','toDoService', function($scope,toDoService){

var tasks = toDoService.getTasks();
$scope.tasks = tasks;

$scope.addTask = function(){
    toDoService.addNewTask($scope.tasks);

}

The structure of your service should resemble the following:

.service('toDoService', function(){

    this.tasks = [];

    this.getTasks =function(){
        var taskList = [
            {"taskName": "do dishes" ,"completed": false, id: Date.now()}
        ];
        return taskList;
    }


    this.addNewTask = function(data){
        tasks.push(data);
        return tasks;
    }

});

    this.addNewTask = function(data){
        tasks.push(data);
        return tasks;
    }

});
