How i can get widgets areas working in customizer?

After a entire night I’ve get the answer.
Reflecting on why the customizer showing me the widget areas only through the wp_footer hook I have checked my footer.php and the problem was that wp_footer() were called before the sidebar section.

   /* Always have wp_footer() just before the closing </body>
    * tag of your theme, or you will break many plugins, which
    * generally use this hook to reference JavaScript files.
    */
    wp_footer();

Moving it after sidebars all works perfectly.
