Overriding self-insert-command doesn't work |

I'd like to override self-insert-command in a way that I replace the
actual function belonging to the symbol `self-insert-command'.
In the code below I do that. I store the old function definition,
replace it with my own definition and call the original definition
from my own function:
(defvar oldfunc (symbol-function 'self-insert-command))
(defun my-self-insert (n)
"doc"
(interactive "p")
(funcall oldfunc n)
(message "hello"))
(fset 'self-insert-command 'my-self-insert)
This solution doesn't work because it seems to affect only self-insert-
command function calls (hello is printed when I press enter which
presumably calls self-insert-command), but it's not printed when I
press any other self insert key (like "a"). Curiously, if I press "C-h
k a" then it says that "a" invokes my function, but it doesn't. Why is
that?
I tested it with Gnu Emacs 21.
I know about advising, so please don't recommend other ways to
accomplish this. I'd like to know why this specific solution doesn't
work.
Thanks.
