Ruby on Rails

Observers will be no more as of Rails 4, farewell, never been much of a fan. However, I'm using it in one of my gems which enables model attributes for use with a WYSIWYM editor. The resulting markup is persisted, but in order to use it in a view, it has to be nokogiried in a helper which fragment caches the result. This cache has to be zapped once the model instance is either updated or destroyed. An observer for after_update and after_destroy seemed the obvious choice at that time.

What would be a Rails 4 approach for this without observers? Inject after_update and after_destroy callbacks directly into the model?
