Update Theme Cart with Shop the Look

For every item added from Shop The Look, you'll get a jQuery event named 'stl.updateCartDetails'.

You can use this event to update your store cart:

$('body').on('stl.updateCartDetails', function(evt, cart) {
  // call the function to reload the cart here
});

document.addEventListener('stl.updateCartDetails', function (cart) {
  // call the function to reload the cart here
}, false);

Also when the app widget is loaded, there is a jQuery event named 'stl.widgetHasBennLoaded' that you can use.
