I'm using ngTouch to remove the delay on mobile devices, but on mobile devices clicking an image does nothing. On my app, clicking an image calls a directive to enlarge the images, so there is no ng-click. Here is the directive:
app.directive('imageZoom', ['ngDialog', function(ngDialog) {
    return {
        restrict: 'A',
        scope: {
            image: '='
        },
        link: function(scope, element, attr) {
            attr.$observe('ngSrc',function(img) {
                element.bind('click', function(e) {
                    e.stopPropagation();
                    if (something) {
                        doSomething();
                    } else {
                        ngDialog.open({
                           some template here
                        });
                    }
                });
            });
        }
    };
}]);
This was working fine until I introduced ngTouch so I believe there is an issue with the element.bind('click' aspect of it where it is not registering the click. It does work perfectly fine on a browser though so the directive does work.
