title: Issue with Binding JQuery-UI Calendar Control with Date Populated
body: <p>I'm having issues with binding the calendar control based on jquery-UI.
  I'm using Knockout and REST API to get the date value and it gets populated correctly in the input text box as below, but the calendar does not reflect the correct binding with the date populated? What needs to be done to reflect the correct date in the calendar.</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;label for="LaunchDate"&gt;Launch Date&lt;/label&gt;
  &lt;div class="input-group"                 
   &lt;input type="text" data-bind="value: Launch_Date"  class="date-picker form-control input-sm" id="LaunchDate"/&gt;
  &lt;label for="LaunchDate" class="input-group-addon btn"&gt;&lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt; &lt;/label&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Knockout JS Code:<br>
      self.Launch_Date = ko.observable(moment.utc(data.d.Launch_Date).format("YYYY-MMM-DD"));</p>
  
  <p>DatePicker Code JQuery UI and Bootstrap:<br>
          $(".date-picker").datepicker();</p>
