The binding is in motion state map, not normal state map (the latter
inherits the former), so try 'motion instead of 'normal.

However, I'm not sure if `evil-lookup-func` is vastly useful. Probably
it's better to remove this variable completely and let the user rebind
"K" if (s)he prefers a different command. This should not be much more
difficult.
