The manuals, though, make it clear that this:

objectValue never gets called when it changes.
should not be expected behaviour. Views observe controllers which
observe models, so there should be no reason for an array controller
to "listen" for changes in a cell. Views communicate changes (within
themselves) to controllers using key-value coding -- see <http://
