JQuery :: .click() Not Working In IE 7?

I have seen this title a few times, but not the same question. I have succesfully bound the .click() method to a radio button group. In IE 7 and FF I can click the button and the .click() function will fire. What doesn't work is a basic .click() (i.e. trigger('click')) event. The code I'm executing is this:

$('#appraisalAge:checked').click();

The above code selects the currently checked button and than .clicks() on it.The HTML that the above code is referencing is:

<div>
<g:radio name="appraisalAge" value="NEW" checked="${offering.appraisedAmount ==null}"/><span><g:message code="offering.appraisal.is.new"/></span>

[code]....
