it actually worked, but only with calling the reset function manually
once. 

try this:

#+begin_src emacs-lisp
(defvar tj/last-buffer-tick nil)
(make-variable-buffer-local 'tj/last-buffer-tick)

(defun tj/new-buffer-ticks-p ()
  (let ((curr-tick (buffer-modified-tick))
	(last-tick tj/last-buffer-tick))
    (setq tj/last-buffer-tick curr-tick)
    (and last-tick (< last-tick curr-tick))))

(defun tj/reset-view-mode ()
  (run-with-timer 0 (* 5 60)
		  (lambda ()
		    (when (tj/new-buffer-ticks-p)
		      (view-mode t)))))

(add-hook 'org-mode-hook 'tj/reset-view-mode)
#+end_src
