Google Maps Javascript - Add listener to user created rectangle


I have a google map that creates a rectangle when a user clicks on the map.

I now want to add a dblclick listener that removes the rectangle when a user double clicks on it. However because the rectangles are dynamically created, I do not know how to reference to them.

Any ideas?

Thankyou. Much simpler then I thought it was going to be.
