kamal.r.php on "[Plugin: Contact Form 7] Change form action from setting"

Hi all,

I am using contact-7 in my wordpress site. The plugin is working fine but I want to change the page url after form submission.

I have used on_sent_ok: "location = 'http://example.com/';" in advance setting

but it is not changing form action attribute.

Can anyone have idea about what is wrong with this...?
