Title: FIX: Enclosure not be removed correctly

You may find all the enclosure will be hidden after you add a sheet and delete it.
The reason is that "jS.controls.enclosures" is a jQuery selector object( "$([])" ) which can't not remove element like an array.All enclosure are reserved after sheet has been deleted.
Here I remove the element by creating the selector object again.
