Wordpress dynamic reply to comment not working

Question

Any idea why?

Of course comment_reply.js included correct way, Firebug not shooting any errors, but dynamic reply not working, redirecting me to the new page :(

Damn!

Edit:

$defaults = array('walker' => null
                    , 'style' => 'ul'
                    , 'callback' => null
                    , 'end-callback' => null
                    , 'type' => 'comment'
                    , 'page' => ''
                    , 'per_page' => ''
                    , 'avatar_size' => 48
                    , 'reverse_top_level' => null
                    , 'reverse_children' => '');
        wp_list_comments($defaults);
