Bootstrap modal close button does not cause postback
<p>I have a boostrap modal, and here is the button to close it:</p>

<pre><code> &lt;div class="modal-footer"&gt;
 &lt;asp:Button ID="btnClose" CssClass="btn" runat="server" Text="Close" data-dismiss="modal" aria-hidden="true" /&gt;
 &lt;/div&gt;
</code></pre>

<p>The Button and modal form are nested in an update panel. But it does not trigger a postback so the update panel does not do its thing. If I remove data dismiss then it will not close the modal.</p>

<p>What could I do?</p>
