destroy
Prepares the DateInput 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 DateInput element from DOM.
Example
<input id="dateinput" />
<script>
$("#dateinput").kendoDateInput();
var dateinput = $("#dateinput").data("kendoDateInput");
// detach events
dateinput.destroy();
</script>
