angular ngClick はデフォルトの動作を使用してバブリングを防止します

var ngEventDirectives = {};
forEach(
   'click dblclick mousedown mouseup mouseover mouseout mousemove mouseenter mouseleave keydown keyup keypress submit focus blur copy cut paste'.split(' '),
   function(name) {
    var directiveName = directiveNormalize('ng-' + name);
    ngEventDirectives[directiveName] = ['$parse', function($parse) {
     return {
      compile: function($element, attr) {
       var fn = $parse(attr[directiveName]);
       return function(scope, element, attr) {
        element.on(lowercase(name), function(event) {
         scope.$apply(function() {
          fn(scope, {$event:event});
         });
        });
       };
      }
     };
    }];
   }
);
