jQuery .clone() issues

This is an example of codes


<div class="mom"> <div class="son"><input class="buttons" type="button" /></div> <div class="son"><input class="buttons" type="button" /></div> <div class="son"><input class="buttons" type="button" /></div> <div class="son"><input class="buttons" type="button" /></div> </div>



and this is jquery code


$(”.son”).first().clone().appendTo(”.mom”) ;
$(”.buttons”).click( function(){
// do sth here.
});


The top 4 elements work fine for .click() but last element(that appended later) seem doesn’t work…..

Any solution there??

Thanks so much

Just fixed it.
Need to use .clone(true)
