Cart Products Summary Block


I was trying to put "Cart Summary" block via layout. Although, it's been added but I don't see it updated, neither via ajax or even after a page refresh.

The same block exists on checkout page, but it works and I can see the summary of the products with total value.

Is there anything I;m missing ? All I want is real time cart summary update, as soon as I click on add to cart and product is added to cart.

Is there anything related with JS hooks ? There is no documentation about it.

Im using latest CS CART 4.7

Thanks in advance
