Comment 3 for bug 1535164

Ah actually the triggers are working as expected (I just didn't switch notifications to inbox)

What the problem turns out to be is the inbox block on dashboard loads via ajax from 15.10 onwards so that the javascript meant to wire up the 'markasread' javascript functions are not connected.

Needed to fire off the 'pageupdated' trigger once the block had loaded so it could wire up the needed functions.
