Bug with checkboxes on cloned items

[psolom]

I have found a bug with checkboxes in current version on cloning items.
As you know for each checkbox yii creates hidden input with default {value="0"} and the checkbox itself has default {value="1"}. So we have:

<input type="hidden" name="Tickets[0][class]" value="0">
<input type="checkbox" id="tickets-0-class" class="selectbox" name="Tickets[0][class]" value="1">

But after cloning all cloned items have both input values as {value}, they lose their default value and after that data aren't sent correctly to controller:

<input type="hidden" name="Tickets[0][class]" value>
<input type="checkbox" id="tickets-0-class" class="selectbox" name="Tickets[0][class]" value>

I managed to fix it in 'afterClone' event in this way:

$('#dynamic-widget').on('afterClone' ,function(e, clonedItem) {
  $(this).find('input:hidden').val(0);
  $(this).find('nput:checkbox').val(1);
});

it works for me, but it is not the best solution I guess.
In fact it is not the widget bug but the jquery bug:

There is described that bug has place in IE but I faced it in Chrome too.
