Broadcast event in angularJS

  $scope.unreserve = function () {
    var params = {
      'wishlist_product_id' : product.wishlist_product_id
    };

    WishlistService.unreserve(params, function (data) {
      if (data.success) {
        $rootScope.$broadcast('NotificationController.create', {type: 'success', message: 'Unreserve successfully'});
      } else  {
        $rootScope.$broadcast('NotificationController.create', {type: 'error', message: data.error_message});
      }
    });
  };

  $scope.createManualProduct = function () {
    var params = {};

    ProductService.addManualProduct(params, function (data) {
      if (data.success) {
        $rootScope.$broadcast('NotificationController.create', {type: 'success', message: 'Unreserve successfully'});
      } else{
        $rootScope.$broadcast('NotificationController.create', {type: 'error', message: data.error_message});
      }
    });
  };

Is there anyway we can refactor this chunk of code to be more clean ?

Thanks for reading :)
