How to put a $ destroy listen when using controllerAs syntax in angular

Question

Now I get rid of the dependency $scopeon my angular controller so that I can easily port my code to Angular2. My current version is angular 1.4.X. Performing the same thing, there is a place when I placed a $destroylistener over my area of ​​the controller, for example $scope.$on('$destory', function() ....).

I see a method $onavailable only on the $scopecontroller, but how can I achieve it without using a dependency $scope.

  };

    $element.on('click', clickHandler);
  };

  this.$onDestroy = function () {
    $element.off('click', clickHandler);
