Observer not firing after checkout

Question

I have created an observer but it does not seem to ever fire - I need to replicate sales_order_place_after from an old Magento 1.9.X module into the one I am refactoring for Magento2

So far I have \MyVendor\Order\etc\events.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="checkout_onepage_controller_success_action">
        <observer name="MyObserver" instance="MyVendor\Order\Observer\OrderObserver" />
    </event>
</config>

And also OrderObserver.php which is:

<?php

namespace MyVendor\Order\Observer;

use \Magento\Framework\Event\ObserverInterface;
use \Psr\Log\LoggerInterface;

class OrderObserver implements ObserverInterface
{
    protected $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
        parent::_construct();
        //Observer initialization code...
        //You can use dependency injection to get any class this observer may need.
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        //Observer execution code...
        $this->logger->debug('Order Observer');
    }
}

I've tried moving the events.xml into a sub folder of etc for frontend, but I seem unable to reach my debug log. What have I done that needs amending to get this observer to fire?

Looks Like you messed up with directory structure that's why its not working for you.

Below is tested with Magento Instance.

MyVendor\Order\etc\frontend\events.xml

 <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="checkout_onepage_controller_success_action">
    <observer name="MyObserver" instance="MyVendor\Order\Observer\OrderObserver" />
</event>
</condfig>

MyVendor\Order\Observer\OrderObserver.php

namespace MyVendor\Order\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Event\Observer;

class OrderObserver implements ObserverInterface
{
  public function execute(Observer $observer)
  {
      echo "Observer Executed"; exit;
  }
}
