A couple months ago I discovered when the changed message is called in a cog. I don't know if anyone already knew, but since it's not in the DataMaster I thought I would post it here.

it's called in an inventory cog when the amount in the bin is changed.

Have you tried it with, for example, changing a 3do model? Most cog messages can deal with several different types of things in JK. Blocked, for example, is used by both doors and with saber blocking, and probably some other stuff.
