title: Datetimepicker binding in knockout.js not working
body: <p>I have a view with a datetimepicker. I am not able to bind it in Knockout. Since the datetime picker end of the day has a textbox, I bind it the same way as other textboxes(which works fine) and assume it to contain the datetime value in text format but it does not get binded.</p>
  
  <pre><code>&lt;div class='input-group date' id='datetimepicker1'&gt;
      &lt;input type="text" class="form-control" id="estimatedTime" data-bind="value: estimatedTime"&gt;
      &lt;span class="input-group-addon"&gt;
         &lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt;
      &lt;/span&gt;
  &lt;/div&gt;
  
  &lt;input type="number" class="form-control" id="estimatedAmt" data-bind="value: estimatedAmount"&gt;
  </code></pre>
  
  <p>This is my script which does not work for datetimepicker(estimatedTime) but works for a normal textbox(EstimatedAmount).</p>
  
  <pre><code>var Model = function () {
          var self = this;
          self.estimatedTime= ko.observable(initialData.estimatedTime);
          self.estimatedAmount= ko.observable(initialData.EstimatedAmount);
  
  self.update = function () {
  
              });                    
        }
  
  ko.applyBindings(new Model());
  </code></pre>
  
  <p>Why is there a difference and what is the easiest way to fix it?</p>
