Hook "fn_generate_navlinks_end" in search

For some reason the hook "fn_generate_navlinks_end" isn't being found/called on the recent search page. The hook is setup in my custom Style folder. It works on every other page.

# Working code, but not on the recent search page
$forum_hooks['fn_generate_navlinks_end'][] = 'unset($links["login"], $links["logout"], $links["register"]);';

Thoughts?
