[jQuery] IE radio button show nothing after click or change

[2daughtersdad]

In IE7 my radio button do not display 'checked' when  I click on it.
(ie I would not change to show which button has been clicked)
I work fine in Firefox. Need Help. Thanks in advance.

I am using jquery-1.3.2.min.js and the following work fine as well.

$("input[name='radioname']").click(function() {
                alert ( $("input[name='radioname']:checked").val()  );
});
$("input[name='radioname']").change(function() {
                alert ( $("input[name='radioname']:checked").val()  );
});
