短代码联系表格7提交无法在管理页面中使用

Cant get submit work of a contact form 7 shortcode. Form is correct displayed. But after submit redirects selft page without notices of successfully submission to database and no mail.

echo do_shortcode('[contact-form-7 id="36650" title="test"]');

i tried several things like this

if ( function_exists( 'wpcf7_enqueue_scripts' ) ) {
    wpcf7_enqueue_scripts();
}

if ( function_exists( 'wpcf7_enqueue_styles' ) ) {
    wpcf7_enqueue_styles();
}

and this

 if(in_array('plugin-directory/plugin-file.php', apply_filters('active_plugins', get_option('active_plugins')))){ 
//plugin is activated
}

but no success the only thin what works is in frontpage copy the html code ofa shortcoded form and insert that in a admin plugin page and as fom action url use the frontpage url. This way it shows the form in admin and at submit it redirects to frontend and ubmit success but its not my really solution.i need it full in backend have someone idea?
