      test('trigger external action when button is clicked', function() {

         //'this.subject()' is available because we used 'moduleForComponent'
         var component = this.subject();

         //Defining the component dom instance
         var $component = this.append();

         var targetObject = {
            externalAction: function(){
               ok(true, 'external Action was called!');
            }
         };

         //External action to be called when button is clicked
         component.set('internalAction', 'externalAction');

         //Set the targetObject to our dummy object
         component.set('targetObject', targetObject);
         click('button');
      });
