title: Why date pipe with input type text does not work with angular2?
body: <p><strong>This works :</strong> </p>
  
  <p><strong>DetailEvent</strong> is a object which has start_time of type <strong>Date</strong></p>
  
  <pre><code> &lt;span class="month"&gt;{{DetailEvent.start_time   | date: 'MMM'}}&lt;/span&gt;
  </code></pre>
  
  <p><strong>This does not work:</strong></p>
  
  <pre><code> &lt;div class="col-md-6"&gt;&lt;input type="text" [(ngModel)]='DetailEvent.start_time| date: 'MMM''&gt; &lt;span class="calender-to"&gt;to&lt;/span&gt; &lt;/div&gt;
  </code></pre>
