Let\'s say I have a $(\'.myUniqueElemen
There is no need to use .insertAfter. You should also not use .clone as it'll remove any attached data or events, unless you use .clone(true).
Simply use .appendTo to add the target element to the div and it'll get detached from its original position and added as the last child of the div:
$('.myUniqueElement').appendTo('#my-div');
