AFAICS there is no functionality to let the preview be regenerated
automatically.

But if that's easier for you, you can click with mouse-2 on the icon at
the start of the opened preview instead or typing `C-c C-c C-p'.

I've looked a bit at the code and saw no obvious and quick way to
provide automatic regeneration.  If somebody is interested in
implementing it, you might want to look at functions like
`preview-check-changes' and especially `preview-move-point'.  In the
former previews are disabled upon a change of the source and this
inhibits them from being toggled in the latter function when point
leaves the previewed region.  Perhaps it would be enough to call
`preview-regenerate' in `preview-move-point' when this happens.  But
I've found no easy way to get hold of the overlay.  It's neither listed
in `preview-temporary-opened' nor in `preview-change-list'.
