destroy
Prepares the DatePicker for safe removal from DOM. Detaches all event handlers and removes jQuery.data attributes to avoid memory leaks. Calls destroy method of any child Kendo widgets.
Important: This method does not remove the DatePicker element from DOM.
Example
<input id="datepicker" />
<script>
$("#datepicker").kendoDatePicker();
var datepicker = $("#datepicker").data("kendoDatePicker");
// detach events
datepicker.destroy();
</script>
