mui的tap事件封装成anguar指令

ngModule.directive('ngTap', ['$parse',function($parse) {
return {
restrict: 'A',
compile: function($element, attr) {
var fn = $parse(attr["ngTap"]);
return function ngEventHandler(scope, elem) {
elem[0].addEventListener("tap",function(e){
var callback = function(e) {
fn(scope, {$event:e});
};
scope.$apply(callback);
});

            };  
        }  
    };  
}]);
