jQuery click event handler is called twice for a checkbox

Question

I have a problem with the following code in an ASPX page:

Answer 1

$(document).ready(function() {
    $('.test').click(function(event) {
                    event.stopImmediatePropagation();
                    alert("Click");
                    })
                 }
              );

I was able to get my code working by stopping the event Propagation. It did not affect the status change of the checkbox.
