The problem is that Evil considers `my-wrapper` as regular Emacs
command. When called in visual state Evil adjusts point and mark so that
the region corresponds to the visual selection right before the command
is executed (and because Emacs region exclusive, point is moved to the
next character).

You could try to register `my-wrapper` as a regular Evil motion, i.e.

  (evil-define-motion my-wrapper (count)
    (call-interactively 'evil-find-char))

should work.
