Why is JQuery mobile not working in Internet Explorer?

For some reason, JQuery mobile is not rendering in Internet Explorer 9 on my website - http://dev.eventhello.com/users开发者_开发问答/login. I tried it in compatibility mode and it still doesn't work.

Any ideas as to why it works in Firefox, Safari, and Chrome, but not in Internet Explorer?

You have Uncaught SyntaxError: Unexpected token } on line 33 of login page source. This results in javascript exception in IE which may stop the page from rendering.

Can you try adding empty string as initial source value:

$( "#EventCity" ).autocomplete({
                        source: "" });

The issue was that there was a bug with JQuery version 1.5 so I updated. More details can be seen at jQuery Templates not working in IE9 RC
