Events are not delegated again if a view is shown in a region, closed, and then re-shown

[diwu1989]

See jsfiddle: http://jsfiddle.net/X9PE6/4/

I create a view object with an events hash, I show it in a region, the events hash works.
I remove the view from the region, region is cleared.
I re-show the view in the region, the view renders, but the events hash is not delegated.

Is this the expected behavior? I had hoped that the events hash are re-delegated when the view gets re-shown and the events hash works again.

This is the intended behavior; close is a bit of a misnomer. Ref #801 and #724.
