title: Bootstrap date-picker on change event on text box is not working?
body: <p>I had a date-picker which was working correctly.And its change event was also working fine. Now i implemented a icon and make text box read-only. Now the change event is not fired neither in read-only textbox case nor in non-read-only textbook case.I have changes only html. </p>
  
  <p>HTML of working case:</p>
  
  <pre><code>&lt;label class="control-label"&gt;Date&lt;/label&gt;
                      &lt;input type="text" class="form-control date-picker" id="StateDatePicker" placeholder="MM/DD/YYYY"&gt;
  </code></pre>
  
  <p>Javascript of working case:</p>
  
  <pre><code>$StateDatePicker = $("#StateDatePicker");
          $(".date-picker").datetimepicker({
  
  
    format: "MM/DD/YYYY"
          })
  This is how i called change event.
  
          $StateDatePicker.on("dp.change", function () {
              //Performing functionality 
          });
  </code></pre>
  
  <p>This was working fine.It was no icon in working case, now i added icon showing in picture:<a href="https://i.stack.imgur.com/XeK8W.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XeK8W.png" alt="enter image description here"></a></p>
  
  <p>Now i have changed the following:
  HTML:</p>
  
  <pre><code>&lt;div class='date-picker input-group date'&gt;
  &lt;input type='text' class="form-control" id="StateDatePicker" /&gt;
                  &lt;span class="input-group-addon"&gt;
                      &lt;span class="glyphicon glyphicon-calendar"&gt;&lt;/span&gt;
                  &lt;/span&gt;
              &lt;/div&gt;
  </code></pre>
  
  <p>Date-picker is working fine, only change event is not called
  There is no change in JS. Why its change event is not called is not working?</p>
