Magento2 plugin/interceptor not working

Question

I have following action:

http://localhost/admin/catalog/product_attribute/edit/attribute_id/135/key/…/

I would like to do some extra things with attribute after saving. I have created and registered custom plugin in Vendor/Module/Plugin/Model/ResourceModel/Attribute/Save.php with following content:

class Save
{
    /**
     * @var Config
     */
     protected $config;


    /**
     * @param Config $config
     */
    public function __construct(Config $config, TypeListInterface $typeList)
    {
        $this->config = $config;
    }

    /**
     *
     * @param Attribute $subject
     * @param Attribute $result
     * @return Attribute $result
     *
     */
    public function afterSave(Attribute $subject, Attribute $result)
    {
        # Do something
    }
}

I have also added following entry to di.xml:

<type name="Magento\Catalog\Model\ResourceModel\Attribute">
    <plugin name="do_stuff_after_attribute_save" type="Vendor\Module\Plugin\Model\ResourceModel\Attribute\Save" />
</type>

But the plugin seems not to work. Even if I die('somenthing'); or try to log to file, the code is not executed after saving the attribute.

Maybe I am trying to overwrite wrong method?

You could follow the points below:

1. You should use di.xml in the adminhtml folder as it is a backend issue.
2. You should override the execute method of this Magento\Catalog\Controller\Adminhtml\Product\Attribute\Save controller class.

File: app/code/Milandev/Testplugin/etc/adminhtml/di.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Catalog\Controller\Adminhtml\Product\Attribute\Save">
        <plugin disabled="false" name="Milandev_Admin_Product_Attribute_Save" sortOrder="10" type="Milandev\Testplugin\Plugin\Catalog\Controller\Adminhtml\Product\Attribute\Save"/>
    </type>
</config>

File: app/code/Milandev/Testplugin/Plugin/Catalog/Controller/Adminhtml/Product/Attribute/Save.php

<?php
namespace Milandev\Testplugin\Plugin\Catalog\Controller\Adminhtml\Product\Attribute;

class Save
{

    public function afterExecute(
        \Magento\Catalog\Controller\Adminhtml\Product\Attribute\Save $subject,
        $result
    ) {
        die('hello world!');
        //Your plugin code
    }
}
