You need to create the file module_dir/etc/frontend/sections.xml with this content:

<?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/controller/action">
 <section name="cart"/>
 </action>
</config>
