Prepares the widget 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 widget element from DOM.

Example - destroy the widget

<input id="textbox" />
<script>
    $("#textbox").kendoTextBox();
    var textbox = $("#textbox").data("kendoTextBox");
    textbox.destroy();
</script>
