magento2.2.4 – The plugin will not fire when you place an order

I'm creating a plugin for Quotemanagement (placeOrder) with the after method, but for some reason it will not fire. I try to die but no luck

Please help, I use Magento 2.2.4

Here is my code

Namespace manufacturer  module name  plugin;
Class QuoteManagement {
Protected $ logger;
protected $ quoteFactory;
protected $ orderFactory;

public function __construct ( Magento  distribution  model  OrderFactory $ orderFactory,
 Psr  Log  LoggerInterface $ -Logger,
 Magento  Quote  Model  QuoteFactory $ quoteFactory) {
$ this-> logger = $ logger;
$ this-> quoteFactory = $ quoteFactory;
$ this-> orderFactory = $ orderFactory;

}
/ **
* Before order success
* /
public function afterPlaceOrder ($ quoteManagement, $ result) {
$ order = $ this-> orderFactory-> create () -> load ($ result);
$ quote = $ this-> quoteFactory-> create () -> load ($ order-> getQuoteId ());
$ addvalue = $ quote-> getAdcodeValue ();
$ order-> setAdcodeValue ($ quote-> getAdcodeValue ());
$ order-> save ();

Return $ result;
}

}

Here is my di.xml file
