Not without other hacks. The updater needs to know the render-context
to be able to register the callbacks. That's a bit ugly in Seaside 2.8
and we were recently discussing on fixing that dependency in Seaside
2.9, but we didn't do it yet. Maybe a feature request in the issue
tracker would put some pressure on us ;-)

It sounds a bit ugly, that the model needs to know about the view.
What about applying the observer pattern (or one of its incarnations),
so that the view gets notified about changes in the model? Like this
your model and view would be separated and you could create the script
from the right context.
