how to get item information from listviw delete event

For deleting a item from ListView in iOS, I set canEdit property. It succeeded in iOS application. But I cannot get ItemID, so I cannot delete that item from RDBMS.

This code get another one item, because target item has already deleted.

listivew.addEventListener('delete', function(event){
    var item = event.section.getItemAt(event.itemIndex);
}

I think getting itemID before delete event fired, But listview doesn't have touch event, and when swipe a row, itemclick event not fired too.

How to get itemID when delete event fired.
