snielsss on "[Plugin: WooCommerce - excelling eCommerce] Auto calculate cart total?"

Is it possible to automatically calculate the cart total, without having to press update cart? I found this:
http://wcdocs.woothemes.com/snippets/show-cart-contents-total/

But it wont update the total automatically. Anybody found a solution for this?

Thanks!
