Try to add the sections.xml file in etc/frontend and add the code below:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
    <action name="your/update_post/url">
        <section name="cart"/>
    </action>
</config>

Hope it will help you.
