destroy
Prepares the BackButton 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 BackButton element from DOM.
Example
<div id="foo" data-role="view">
<a id="backbutton" data-role="backbutton">Back</a>
<a data-role="button" data-click="destroy">Destroy it</a>
</div>
<script>
var app = new kendo.mobile.Application();
function destroy() {
$("#backbutton").data("kendoMobileBackButton").destroy();
}
</script>
