 Change your mind , My is , Bind events to input above , solve the problem , And then use for  Label pointing input Elements 
<li class="option" >
   <input type="radio" id="inputid"/>
   <label for="inputid"> Click on label, And click inpu effect   equally </label>
</li>

$('li.option input').click(function() {
alert(" It's only going to be executed once ")                
});
