How to call TextChanged of TextBox WebForm Control
<p>I use <code>TextBox</code> WebForm Control configured like a Bootstrap <code>Datetimepicker</code>.
And I need to initiate server side <code>TextChanged</code> event.
The code I have does not work so it does not call server side part.</p>

<p><strong>HTML</strong></p>

<pre><code>&lt;div class='datepicker input-group date' id='datetimepickerStart'&gt;
                                    &lt;asp:TextBox ID="StartDate" class="form-control dateField" placeholder="Fecha" required runat="server" OnTextChanged="StartDate_TextChanged"&gt;&lt;/asp:TextBox&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><strong>C#</strong></p>

<pre><code>protected void StartDate_TextChanged(object sender, EventArgs e)
{
    // It does not fire :(        
}
</code></pre>

<p>I try to force this event like this but no joy.</p>

<p><strong>JS</strong></p>

<pre><code>$('#datetimepickerStart').datetimepicker();

$('#datetimepickerStart').datetimepicker().on('dp.change', function (event) {
       console.log(event.date);
      $('#StartDate').change(); // It does not help
      $('#StartDate').html(event.date); // It does not help             
});
</code></pre>

<p>Any clue how to fix it?</p>
