Updating minicart items number

[jurg3n]

Hi!

How to update minicart items number (red square at upper right corner)?

After copying /app/code/Magento/Checkout/Controller/Cart/UpdatePost.php (with not changed code) to custom module when I press 'Update Cart' button, cart updates properly but minicart stops updating.

Thanks.
