By "doesn't work", do you mean that it would trigger an infloop?
Would something like this work:

    (defvar iedit-inhibit-update nil)

    (defun iedit-update-occurrences-2 (occurrence after beg end &optional change)
     ...
     ;; Let other modification hooks run, but don't recurse infinitely.
     (unless iedit-inhibit-update
       (let ((inhibit-modification-hooks nil)
             (iedit-inhibit-update t))
       ...
