this is the code :
$(".adauga_incasare").click(function(){
var html = $(".incasari")[0].outerHTML;
$(html).insertAfter($(".incasari").last());
});
$(".del_incasare").click(function(){
alert("dsdasdasd");
});

the outerHTML works fine, but when i "clone" the class incasari after that , when the onclick event doesnt work on the clone part. I have a delete button. In the first class "incasari" in works , but in the clone class it does not . Why ?
