Other have already shown how to correct your code, but here's some
advice with which you can maybe help yourself in future:

When I evaluate this code and then type `C-<tab>', I see this message:
"Invalid function: (backward-word)".  That tells you what the problem
is.  If you don't understand it, try reading the node "Run a Program" in
the Info manual "An Introduction to Programming in Emacs Lisp", which
you can access by putting the cursor after the closing parenthesis of
the following expression and typing `C-x C-e':

(info "(eintr) Run a Program")

In particular, this part of the node should help you see the problem
with your code:

  The single apostrophe, ‘'’, that I put in front of some of the
  example lists in preceding sections is called a “quote”; when it
  precedes a list, it tells Lisp to do nothing with the list, other than
  take it as it is written.  But if there is no quote preceding a list,
  the first item of the list is special: it is a command for the computer
  to obey.  (In Lisp, these commands are called _functions_.)  The list
  ‘(+ 2 2)’ shown above did not have a quote in front of it, so Lisp
  understands that the ‘+’ is an instruction to do something with the rest
  of the list: add the numbers that follow.
