I got it, wasn’t registering my scripts properly 😉
wp_register_script( 'wl-googlemaps-api', '//maps.googleapis.com/maps/api/js?v=3.exp&sensor=false', array(), '3', true);
wp_register_script( 'wl-googlemaps', get_template_directory_uri() . '/js/googlemaps.js', array('wl-googlemaps-api', 'jquery'), '0.1', true );
