第一次从按钮提交时，只有单击两次后才会打开模态框

我有一个模式弹出窗口可以通过单击按钮打开。不幸的是，当第一次在浏览器中提交时，我只能在单击两次后才能看到弹出窗口。但是，一旦弹出窗口打开并关闭，我就可以在下一次尝试中单击一次来打开模式。如果我刷新浏览器也会发生同样的情况。这看起来很奇怪。任何人都可以解释为什么？我有以下代码，

按钮 HTML：

<div><button class="btn btn-danger btn-sm" ng-disabled="{{update_problem_description_disabled}}" ng-click="siverifyAddReviewModal()"><i class="glyphicon glyphicon-edit"></i> Edit Review </button>
    </div>

模态 HTML：

<div class="modal-header container-fluid">

   {% include "siverify_modal_header.html" %}
</div>
<form class="well form-horizontal" name="addReviewForm">
   {% csrf_token %}
   <div id="form-modal-body" class="modal-body">
      {% verbatim %}
      <table class="table" style="width:90%">
          <tr>
              <th><label>Review Title/Purpose*</label></th></br>
                {% endverbatim %}

              <td><input type="text" class="col-md-10" maxlength="256" ng-model="arform.revtitle" value="arform.revtitle"  required/></td>

              <!--<td><input type="text" class="col-md-10" maxlength="256" ng-init="'{{reviewtit}}'" ng-model="arform.revtitle"  > {{reviewtit}} </td>-->

          </tr>
<div class="modal-footer">
      <button type="submit" class="btn btn-primary"
              ng-disabled="addReviewForm.$invalid || rev_submit_disabled"
              ng-click="addReview(arform)">Save</button>
      <button type="button" ng-click="cancel()"
              class="btn btn-small btn-warning">Cancel</button>
   </div>
 </form>

模态函数

$scope.siverifyAddReviewModal = function(wpts,mask,lyr,tech) {
        // function to open modal and link to Modal Controller

        $scope.addRevModal = function(wptSet) {
            context = $scope.get_problem_stmt_context(dtWorklist, context_getter);
            //console.log("dtw", dtWorklist);
            var modalInstance = $modal.open({
                backdrop: 'static',
                templateUrl: '{% url 'siverify_add_review' %}',
                controller: 'SiVerifyAddReviewController',
                resolve:{
                        r_header: function(){ return wptSet; },
                        context: function(){ return context; }
                }
            });
           modalInstance.result.then(function () {
                datatable_worklist.refresh();
                $log.info('Modal success');

                //console.log(msg);
                }, function () {
                    $log.info('Modal dismissed at: ' + new Date());
            });
        };
        //End:function to open modal and link to Modal Controller
