title: Update details in cart widget without loading page by using ajax in Woocommerce
body: <p>I am developing a woocommerce widget which will show cart subtotal, cart total, cart items, and shipping total its working fine but what I want to do is to update shipping total as well as cart total whenever I toggle between shipping methods with use of ajax. Currently it updates itself only after page reload. Is there any hook available for this purpose ?</p>
