Problem with dragging multiple items useing revert and helper options? (includeing examble)

Hello,
First of all, my script dose include messages system that should be having selectable and draggable with useing some good feature by jquery UI.

Well, using selectable is working pretty fine without any problems, but once i added the draggable, I got 2 problems.

The problems that i have:
1- When i select multiple items and then drag them, it wont drag all items, It just drag the item that i push, And the items should revert back, because im using (revert and helper options).
2- Im doing a simple counter for the selected items it count pretty well with the (ctrl key), Example for the problem: lets say i have 4 items and i selected all of them, the counter will count 4 items, and when i unselect 1 item the counter should be 3, But it wont.

So i covered all of the important issues, And here is an example of the my selectable and draggable with the 2 issues
