我创建了一个复选框的指令,它创建了一个图像层,但问题是,即使输入框检查值被更改,它也不会触发更改事件

指示

function icheck($timeout,$parse) {
return {
        restrict: 'A',
        link: function ($scope, element, $attrs, $watch) {
            var value = $attrs['value'],
                ngModelGetter = $parse($attrs['ngModel']);

            return $timeout(function () {

                $scope.$watch($attrs.ngModel, function (newValue) {
                    $(element).iCheck('update');
                });

                $(element).iCheck({
                    checkboxClass: 'icheckbox_square-green',
                    radioClass: 'iradio_square-green'
                }).on('ifChanged', function (event) {

                    var elemType = $(element).attr('type');

                    if (elemType === 'checkbox' && $attrs.ngModel) {
                        $scope.$apply(function () {
                            console.log(event.target.checked)
                            return ngModelGetter.assign($scope, event.target.checked);

                        });
                    }
                    else if (elemType === 'radio' && $attrs.ngModel) {
                        return $scope.$apply(function () {
                            return ngModelGetter.assign($scope, value);
                        });
                    }
                }); …

我想点击一下课程,请找到我的下面的代码.

<li class="dropdown" data-ng-class="sign-open">
  <a href="" class="dropdown-toggle" data-ng-click="signToogle()">Sign In <b class="caret"></b></a>
  <div class="dropdown-menu" style="padding: 15px;">
    <form action="#" method="post" accept-charset="UTF-8" class="form-menu">
      <input id="user_username" type="text" name="user[username]" size="33" placeholder="Username">
      <input id="user_password" type="password" name="user[password]" size="33" placeholder="Password">
      <label class="checkbox muted hidden-tablet">
        <input type="checkbox">Remember Me</label>
      <input class="btn span3" type="submit" name="commit" value="Sign In">
    </form>

  </div>
</li>


//sign in show-hide
$scope.signToogle = function () {
    if ($scope.sign-open === "")
        $scope.class = "open";
    else
        $scope.class = "";
}

这个js函数将addclass打开,所以如果ul有开放类,因为它是父类,那么它将是可见的.但是不知道我怎么能做到这一点,如果点击一次然后真实和类附加,如果再次点击语句false和类将被删除.
