Sorry if this is basic.
After reading here i changed :
$('input,textarea').keyup(function()
to
$('input,textarea').on('keyup', function()
On my cloned element :
var cln = item.cloneNode(true); //true
and i can only listen to divs
that where in my document on load, not the ones who cloned later.
I have also tried :
var cln = item.cloneNode(true, true);
after reading this : jQuery clone() not cloning event bindings, even with on()
