How to make the jQuery valid function work reliably on IE?

I have a problem on jQuery valid function. When on IE, it doesn't work, the valid always return true. I used this code: client side validation with dynamically added field

Here's the chart:

                    Chrome      IE

jquery-1.6.1        works       not working
jquery-1.4.4        works       works

1.6 doesn't work on IE too. However, 1.4.4 jQuery valid works on IE.

Here's the jsFiddle-friendly test (test this as local html):

<form id="XXX">
    <input type="submit" id="Save" value="Save">

</form>


<script type="text/javascript">

        $.validator.unobtrusive.parseDynamicContent = function (selector) {
            //use the normal unobstrusive.parse method
            $.validator.unobtrusive.parse(selector);

            //get the relevant form
            var form = $(selector).first().closest('form');

            //get the collections of unobstrusive validators, and jquery validators

            var unobtrusiveValidation = form.data('unobtrusiveValidation');
            var validator = form.validate();

            $.each(unobtrusiveValidation.options.rules, function (elname, elrules) {
                if (validator.settings.rules[elname] == undefined) {
                    var args = {};
                    $.extend(args, elrules);
                    args.messages = unobtrusiveValidation.options.messages[elname];
                    $('[name=' + elname + ']').rules("add", args);
                } else {
                    $.each(elrules, function (rulename, data) {

                            var args = {};
                            args[rulename] = data;
                            args.messages = unobtrusiveValidation.options.messages[elname][rulename];
                            $('[name=' + elname + ']').rules("add", args);
                        }
                    });

UPDATE

I tried my code on jsFiddle, it has side-effect, the jQuery 1.6's valid is working on IE. Don't test this code on jsFiddle. Test this code on your local html

This problem has been solved. try version 1.8.1.

Download jQuery validation plugin

Hi I also got the same problem and I have updated my both scripts file to the latest one and everything is working very fine on my side. Go to jquery.com and check for the latest jquery code file.
