Click Event For Cjuibutton Of Type Button Set

So I have


$this->beginWidget('zii.widgets.jui.CJuiButton', array(

	'buttonType'=>'buttonset',

	'name'=>$bname.'-set',

	'htmlOptions' => array('id' => 'buttonSet'.$bname),

	'onclick' => "javascript:stageButtonSetClick(this)",

));

in a view and inside this widget I set up some labels and radio buttons. Everything appears to render properly with the nice rounded corners and the exclusivity of the button click.

I want to attach a bit o js code to the click event of the buttons. I know that CJuiButon is cuasing the click on the radio button label I need to be able to attach a click event to label.

How do I attach a click event to the label of a radio button?
