Fix manage click listener for promoted bubble

The manage button is created by the expanded view, but the listener
is set by stack view. Sometimes there are cases where the button
is recreated by the expanded view, which removes the existing listener.

This change now sets the click listener within the expanded view
whenever the manage button is set.
