call/cc does not return a value

hello,

i believed call/cc allowed to return value but i have this macro and i can
use continuation, but the value is not passed to the continuation:

(define-syntax for
   (lambda (stx)
     (syntax-case stx ()
       ((kwd (init test incrmt) body ...)

        (with-syntax ((BREAK (datum->syntax (syntax kwd) 'break))
                      (CONTINUE (datum->syntax (syntax kwd) 'continue)))

    (syntax
     (call/cc
      (lambda (escape)
(let-syntax ((BREAK (identifier-syntax (escape))))
  init
  (let loop ()
    (when test
      (call/cc
(lambda (next)
 (let-syntax ((CONTINUE (identifier-syntax (next))))
   (let () ;; allow definitions
     body ...)))) ; end call/cc
      incrmt
      (loop))) ; end let loop
  ))))) ;; close with-syntax
))))

here i should get "finish" at REPL but nothing happens?
