Yeah, because it's, ehm, nonsense.

You want to bind your key in a keymap, and do that in the hook, e.g.

(add-hook 'emacs-lisp-mode-hook
          (defun my-emacs-lisp-mode-hook-fun ()
            (define-key emacs-lisp-mode-map (kbd "H-z") #'rec-field-nwltok)))

Hooks contain functions.  I use to use named functions because lambdas
cannot be identified should you reload your piece of code and thus get
added multiple times.  If you don't care (i.e. if you know for sure you
don't reload your init file) a lambda also works.
