It doesn't. You bind `mode' to a list (!) of one element, the function.
You want to bind `mode' to the function itself. (OTOH, for the
interactive spec, you would want to return a list: the list of read
arguments, which are then bound to the argument variables.)
And then, `unless' should be a `when'.
