how to do ON MODIFY CASCADE?

I've got a table with a foreign key to another table, and I'd like that if the value of the primary key referenced changes the value, the
values in my table change to this new value automatically.

I was searching for this and all that i've found is ON DELETE CASCADE but nothing
about an ON MODIFY CASCADE.

What can I do??

Thankyou
