Bootrap datetimepicker not triggering asp textbox's onTextChanged event

I can't seem to get my textbox to automatically postback after selecting a
date from the bootstrap datetimepicker (Downloaded from here). I stil have
to press enter for the event to trigger.
<div class="span3">Date<br />
<div id="datepicker" class="input-append date">
<asp:TextBox ID="txtDate" runat="server"
OnTextChanged="txtDate_TextChanged" AutoPostBack="true" />
<span class="add-on">
<i data-time-icon="icon-time"
data-date-icon="icon-calendar"></i>
</span>
</div>
</div>
