can i rewrite doing scope.method()(params)?

directive.js

/* directive */
function modalOverlay ($sce, $parse, uuid) {
  return {
    restrict: 'E',
    transclude: true,
    scope: {
      data: '=',
      onComplete: '&'
    },
    templateUrl: 'views/directives/modal_overlay.html',
    link: function (scope, element, attrs) {
      ...
    
      scope.onSuccess = function(response){
        scope.onComplete()(response.data) // can I rewrite this onComplete()() thing?
      }
      
      ...
    }
  }
}

angular
  .module('adminPanelAngularApp')
  .directive('modalOverlay', modalOverlay);

index.html

<modal-overlay data="modalData" on-complete="modalComplete"></modal-overlay>

index.js

....

  scope.modalComplete = function(e){
    // e is the data send from directive.js#15
    debugger
  };

....
