I was using the live() function:
live()
$(\'a.remove_item\').live(\'click\',function(e) {});
I needed to change this to one()>
one()>
I use it on $.ajax function, so, on the final, in my case fail, I use ,500 in order to delay it and stop to resend many times.
}).fail(function(response, status){ alert("FAILED: "+JSON.stringify(response, null, 4)); },500);
I hope it helps you!
