starts with a ul list  visibility:hidden , use jquery to bind the click event to the li, click a button to display it, and then click li to trigger the bound click event. 
 then remove the initial  visibility:hidden , and the bound event is fine. 
is there any solution, or is there something wrong with my writing?
