为什么我的指令会丢失$ event？

Question

我有一个自定义指令来确认点击元素的用户是否真的想要执行操作：

  .directive('ngReallyClick', ['$modal',
    function ($modal) {

        return {
            restrict: 'A',
            scope: {
                ngReallyClick: "&",
            },
            link: function (scope, element, attrs) {
                var isDeleteDisabled = scope.ngReallyDisabled;
                element.bind('click', function () {
                    if (isDeleteDisabled != true) {
                        var message = attrs.ngReallyMessage || "Are you sure ?";
                        ...
                        var modalInstance = $modal.open({
                            template: modalHtml,
                            controller: ModalInstanceCtrl
                        });

                        modalInstance.result.then(function () {
                            scope.ngReallyClick({ ngReallyItem: scope.ngReallyItem }); //raise an error : $digest already in progress
                        }, function () {
                            //Modal dismissed
                            return false;
                        });
                    };
                });

            }
        }
    }]);

用于例如：

<a ng-really-message="Are you sure you want to save and close?" ng-really-click="saveAndCloseGlobal(456)"

当用户确认他们的选择时调用saveAndCloseGlobal。但是，如果我尝试将$event传递给此函数，以获取原始click事件，则最终未定义。如果我使用普通ng-click=saveAndCloseGlobal($event)，那么我会在saveAndCloseGlobal中获得正确的事件对象。
