I gotta go with John on this one. Just use the callback. It's simpler,
clearer, and that's really what it's designed for.

Okay, so yes, the callback is usually used for validation. But it's
not really overloading it if you have multiple submit buttons which
you can then detect for and thus act accordingly.
