subfooter with wrap

i have tried that: http://cobaltapps.com/forum/forum/main-category/web-design-talk/17301-how-do-i-add-div-wrap-in-custom-widgets
with hook box and shortcode, but nothing appears, and i don’t understand why

then i tried that withe code method, and paste this code in functions.php

genesis_register_sidebar( array(
'id' => 'subfooter',
'name' => __( 'subfooter', 'epik' ),
'description' => __( 'widgets before footer', 'epik' ),
) );

add_action( 'genesis_before_footer', 'alex_genesis_widget_area' );
function alex_genesis_widget_area() {
                genesis_widget_area( 'custom-widget', array(
		'before' => '<div class="subfooter_wrapper"><div class="wrap">',
		'after'  => '</div></div>',
    ) );

}

In both cases the widget area appears u-in the back off, but nothing in front 🙁

Hi,
yes it works with hook boxes !
before it was not working because my host has release a new cache and i don’t know that it was activated 🙁
