I have a jQuery UI Dialog working great on my ASP.NET page:
jQuery(function() {
    jQuery("#dialog").dialog({
        draggable: true,
        resizable: true,
        show: 'Transfer',
        hide: 'Transfer',
        width: 320,
        autoOpen: false,
        minHeight: 10,
        minwidth: 10
    });
});
jQuery(document).ready(function() {
    jQuery("#button_id").click(function(e) {
        jQuery('#dialog').dialog('option', 'position', [e.pageX + 10, e.pageY + 10]);
        jQuery('#dialog').dialog('open');
    });
});
My div:
<div id="dialog" style="text-align: left;display: none;">
    <asp:Button ID="btnButton" runat="server" Text="Button" onclick="btnButton_Click" />
</div>
But the btnButton_Click is never called... How can I solve that?
