Triggering afterStateUpdated() with $set()?

Hi, I'm trying to to use the

afterStateUpdated()

afterStateUpdated()

method on a TextInput Field, that has been updated/filled by the

$set()

$set()

method from another field. Updating the value using

$set()

$set()

does not seem to trigger the

afterStateUpdated()

afterStateUpdated()

method (unless I'm doing something wrong). Is this not possible? Or how can I achieve this?
