title: How to clear up textarea ng-model
body: <p>I've got </p>
  
  <pre><code> &lt;div class="navbar-collapse"&gt;
     &lt;div class="row"&gt;
       &lt;div class="col-lg-2 img-fake"&gt;&lt;/div&gt;
          &lt;div class="col-lg-10 native-item "&gt;
              &lt;textarea class="form-control" rows="5" id="comment" ng-model="newComment" ng-keyup="$event.keyCode == 13 &amp;&amp; comment(existingItem,newComment)"&gt;&lt;/textarea&gt;
            &lt;/div&gt;
        &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>and in the <code>comment</code> function i've got </p>
  
  <pre><code> $scope.comment = function(existingItem,newComment){
        existingItem.comments.push(newComment);
        $scope.newComment = '';
      } // just adding text from textarea to the list 
  </code></pre>
  
  <p>so i'm wondering why the value of textarea does not go to empty value</p>
