AngularJS ng-include: onload calling a function defined in included controller

Question

Using AngularJS, is it possible to use the "onload" argument to trigger a function defined inside a "child" controller (a controller called by the included template)?

Example:

<!-- parent container -->
<div ng-include="'/path/template.html'" onload="childOnLoad()"></div>

<!-- template.html -->
<div ng-controller="childController">   
    <p ng-bind="txt"></p>
</div>

<!-- childController.js -->
app.controller('childController', function($scope) {    
    $scope.txt = "Test text";

    $scope.childOnLoad = function() {
        alert("Loaded!");
    };  
});

Does it make sense? Or should I simply call the function inside the childController, as in the following?

<!-- childController.js -->
app.controller('childController', function($scope) {    
    $scope.txt = "Test text";

    $scope.childOnLoad = function() {
        alert("Loaded!");
    };

    $scope.childOnLoad();   
});

Answer 1

Leave the parent container the way you defined it:

<div ng-include="'/path/template.html'" onload="childOnLoad()"></div>

In the parent controller define:

$scope.childOnLoad() {
  $scope.$broadcast("childOnLoad", data);
}

and in the child controller:

$scope.$on("childOnLoad", function (event, data) {
  alert("Loaded!");
});

Answer 2

In your second attempt you did right: you are creating some functions, the scope of that controller is taking those functions as properties, then $scope.childOnLoad(); will call the function you created.

In fact you can define so many functions but they are not called while loading or when loads complete.
