 * Acording this changes :
 * - https://core.trac.wordpress.org/ticket/26571
 * - https://core.trac.wordpress.org/ticket/26495
 * now you can't use 'right_now_*' action API to show your custom post type count from your Dashboard.
 * But if you running WP 3.8 or above, you can use 'dashboard_glance_items' instead.
