Ok, now it's working, but only if you go to "User control panel > Subscriptions > Actions > Renew..."
If I create a menu for the front-end of type "HikaSerial > Subscription listing", this is not gonna work, it will show the subscriptions, but when you try to use the "Actions > Renew", it will happen the same.
Here the link of "Renew" button is:
domain.com/component/hikashop/subscription/renew/subscription-1/product-1?Itemid=132
The url after redirect is this:
domain.com/component/hikashop/checkout?cart_id=2&Itemid=132
