[web2py] question about trapped ajax link

[weheh]

I'm trying to get a trapped ajax link, which deletes a record, to
update two different divs on the screen. One div is rendered by its
controller. But how about the other div, assuming that it is usually
rendered by an entirely different controller? I tried using
response.js and response.headers['web2py-component-command'] to render
the other div, but it didn't work. I'm missing something.
