body: <pre><code>&lt;td rowspan="5" colspan="2"&gt;
      &lt;div id="style-2" class="scrollit"&gt;
          &lt;table class="table-borderless table-condensed" style="height:100px; width:100%; overflow-y:scroll"&gt;
              &lt;tr&gt;
                  &lt;td colspan="2" class="verticleAlignMidle"&gt;
                      &lt;h6&gt;&lt;b&gt;{{ctrl.commentsBox.length}} Comments:&lt;/b&gt;&lt;/h6&gt;
                  &lt;/td&gt;
              &lt;/tr&gt;
              &lt;tr ng-repeat="item in ctrl.commentsBox"&gt;
                   &lt;td class="width8"&gt;
                       &lt;div class="commentCol divStyle"&gt;{{item.name}}&lt;/div&gt;
                   &lt;/td&gt;
                   &lt;td class="width11"&gt;
                       &lt;span&gt;&lt;b&gt;{{item.FullName}}&lt;/b&gt; {{item.date}}&lt;/span&gt;
                       &lt;br /&gt; &lt;span&gt;{{item.comment}}&lt;/span&gt;
                   &lt;/td&gt;
               &lt;/tr&gt;
           &lt;/table&gt;
       &lt;/div&gt;
   &lt;/td&gt;
  </code></pre>
  
  <p>This is my list. That need to be updated on adding comment and pressing enter:</p>
  
  <pre><code>&lt;td class="width33 verticleAlignMidle" colspan="2"&gt;
      &lt;textarea cols="80" rows="5" ng-keyup="$event.keyCode == 13 ? ctrl.saveAdGroup() : null"
      ng-model="ctrl.textComment" ng-view="ctrl.textComment" placeholder="Write a comment"&gt;&lt;/textarea&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>And the function is :</p>
  
  <pre><code>ctrl.saveAdGroup = function () {
       var ctrl = this;
       var c = ctrl.textComment;
       ctrl.textComment = "";
       var n = "DN";
       var fullName = "Dummy Name";
       var formatDate = ctrl.dates();
       var objComment = { name: n, date: formatDate, comment: c, FullName: fullName };
       ctrl.commentsBox.push(objComment);
       alert(ctrl.commentsBox.length);
  };
  </code></pre>
  
  <p>I m getting increased length in the alert but not reflecting in the ui.</p>
