vWishlist doen't work

Hi,
I purchased your vWishlist component and I installed it in my development website.
I noticed that it doesn't work fine.
You can see it here: sviluppo.famideal.it/shop/detersivi-ecol...rica-pulito-naturale
If you check the checkbox nothing happens. Could you help me to solve this?

Besides I have an important questions:
Must I add your wishlist in each product manually?
Consider that I have an e-commerce with more than 3000 products...
If it's so I think it's crazy and I can't use it

In my website I need two components to manage two different kind of wishlist.
The classic wishlist and the birth wishlist for mummy, so I'm looking for a component which could work together the component yet installed.

Could you let me know if I can use your vWishilist?

Thank you.

Best,
Anna.
