Best way to notify the Controller when one Array object value is changed

Hello, so i have one ArrayController that is bound to one Array, and a
tablecolumn that is bound to the ArrayController objects (not any particular
value).

As a normal behavior the controller gets notified when i add or remove
objects, but i have a thread that every second updates the objects. What is
the correct way to notify the Controller that a specific object values where
changed?

I'm guessing the Thread shouldn't have direct access to the Controller since
its in a "lower" abstraction layer, so how do i notify or make the
controller track changes to values?

The column is not bound to values because it has custom dataCells that need
several properties from the array objects.

Ty.
