jQuery 1.6.4 and RadioButtonList issue
Moving from jQuery 1.4.4 to jquery 1.6.4 started breaking my code related to radiobuttonlist.

Here is a sample code and steps to replicate weird behavior:

Steps to reproduce:

1: Radio A is already selected.

2: Select radio B

3: Enter something in textbox and tab out.

You will see: **A is checked and B is checked alerts.**

So what exactly changed from 1.6.4 to 1.4.4 that is causing it to break?

        <script type="text/javascript">
            function txtchanged(tb) {
                $(".rbl").find("input[type='radio']").each(function () {
                    alert($(this).val() + " " + $(this).attr("checked"));
                });
            }
