Deep cloning an input that has a UI datepicker doesn't work as expected.
<br>
Input 1:
<input>

JavaScript

var $input = $("input").datepicker(),
    $clone = $input.clone(true).data( "datepicker", $.extend( true, {}, $input.data("datepicker") ) ).attr('id', 'test-id');

$clone.data('datepicker').input = $clone;
$clone.data('datepicker').id = 'test-id';

$("body").append("<br><br><br>Input 2: ").append(
    $clone
);
