Which is this:

(defun foo (beg end)
  (interactive "r")
  (let ((overlay (make-overlay beg end)))
    (overlay-put
     overlay 'display
     (propertize "xxxxxxxxx" 'face 'font-lock-constant-face 'keymap foo-map))))

Yidong's suggestion still has the (overlay-put overlay 'keymap foo-map); yours
does not. Is that part needed? (Trying to understand what is needed, not just
what works on this example.)

What is "it"? Your suggestion or Yidong's (or both)?
