Jquery easy confirm dialog.js IE6 issues

Hi,
I am using jquery.easy-confirm-dialog.js plugin for confirm dialog.In IE6 it doesn't opens up the confim dialog when I click on the button.

IE6 it shows the error at line number 144 in jquery.easy-confirm-dialog.js

var handler = function(event) {
        alert(event);
             $(dialog).dialog('open');
            event.stopImmediatePropagation();
            event.preventDefault();
            return false;
        }
I dont know what is the reason and how to resolve it.In FF it works fine,

Thanks,
Thiru
