If you repaint the component from the server, and want to
retain its input, you have to submit to the server and store
it to the model (with a suitable *submittingbehavior) so
that it will have the correct value on the repaint. Because
the Ajax response content always comes directly from the
server it has only access to submitted data. So, if you have
one checkbox that toggles several input elements, you must
use a behavior that submits the whole form.
Another option is to do it purely on the client side --
toggle the input DOM element properties with javascript
attached on the correct event handler ("onclick" I think?)
of the checkboxes. Your favourite Javascript library (e.g.

can come handy there.
Best wishes,
