Small help with EventTrigger

I am trying to add my method with parameter int to PointerClick event trigger but whatever I do it giving the error. When I try to add method with parameter BaseEventData all work fine. What I am doing wrong?

Code (CSharp):

1. EventTrigger.Entry entry = new EventTrigger.Entry();
2. entry.eventID = EventTriggerType.PointerClick;
3. entry.callback.AddListener(delegate { SendItemDrop(DropList[0].iBundleID); });
4. dropObject.AddComponent<EventTrigger>().triggers.Add(entry);
