Extras don't work. Contact Form 7 settings, why?

Question

WordPress

hr-prestige.ru
profile (on the left in the menu)
when filling out, you need to pop up a window about successful sending or write inside the form
in the add. fields must be written on_sent_ok: "alert('sent ok');"
I prescribe - it does not work
when sending data, the form is redirected to an empty page, when tearing it off again - it writes all the necessary messages
redirect back to the form on_sent_ok: "location = ' hr-prestige.ru/#!/form ';" also doesn't work
why?

Interesting, so without

// jQuery
    $scripts->add( 'jquery', false, array( 'jquery-core', 'jquery-migrate' ), '1.11.1' );
    $scripts->add( 'jquery-core', '/wp-includes/js/jquery/jquery.js', array(), '1.11.1' );
    $scripts->add( 'jquery-migrate', "/wp-includes/js/jquery/jquery-migrate$suffix.js", array(), '1.2.1' );

does not work?
