destroy
Prepares the Calendar 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 Calendar element from DOM.
Example
<div id="calendar"></div>
<script>
$("#calendar").kendoCalendar();
var calendar = $("#calendar").data("kendoCalendar");
calendar.destroy();
</script>
