destroy
Prepares the MultiColumnComboBox 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 MultiColumnComboBox element from DOM.
Example
<input id="multicolumncombobox" />
<script>
$("#multicolumncombobox").kendoMultiColumnComboBox();
var multicolumncombobox = $("#multicolumncombobox").data("kendoMultiColumnComboBox");
multicolumncombobox.destroy();
</script>
