What are the functionalities implemented in the directive?

Apologies for needing help with what seems like a simple question, but I'm struggling to figure it out. I have a directive that receives data from a $broadcast event and needs to use that data to create a new template.

  app.directive('emptyScope', function() {
    return function( $scope ) {
       return $scope.$on('checkEmptyArray', function(event, data) {
          return {
            template: '<img src="../images/apple.png">'
          };
      });
    }
});

The data from 'checkEmptyArray' is being received perfectly fine, and I can confirm this through console.log. However, for some reason, it's not executing the code within:

return  {
            template: '<img src="../images/apple.png">'
          };

I'm baffled as to why it's not working. Can anyone shed some light on this? Thanks.

Since it's a callback, returning anything is not possible. To display your image, you must include the rendering logic within your function.

app.directive('emptyScope', function() {
    return function( $scope ) {
       return $scope.$on('checkEmptyArray', function(event, data) {
          $scope.myImg = data;
      });
    }
});


 <div ng-bind-html="myImg"></div>
