Cake PHP 2 event listener not firing

Question

I'm working on a Cake PHP 2 project that contains a custom module feature allowing for custom plugins. The functionality for this to work is loaded correctly, and the module I'm working on called QueueManager contains a controller linked to a button which dispatches an event, I'm then listening for this event in a file called app/modules/QueueManagerModule/Lib/Event/DispatchJobListener.php and it's here where I'm simply trying to write to a file to check if the listener is listening.

I'm not getting any errors logged to my error.log file, what am I missing?

My controller contains the following to dispatch the event:

<?php

App::uses('AppController', 'Controller');
App::uses('CakeEvent', 'Event');

class QueueController extends AppController
{
    /**
    * Define the name
    */
    public $name = 'Queue';

    /**
    * Define the name
    */
    public $layout = 'QueueManagerLayout';

    /**
    * Loaded models
    */
    public $uses = array(
        'QueueManagerJob',
        'QueueManagerFailedJob'
    );

    /**
    * View: Queue/dashboard
    */
    public function dashboard()
    {
        if ($this->request->is('post')) {
            $this->getEventManager()->dispatch(new CakeEvent(
                'QueueManagerModule.QueueManagerJob.dispatch',
                $this, array('payload' => ['name' => 'john'])
            ));
        }
    }
}

My Lib/Event/DispatchJobListener.php is listening for the event:

<?php

App::uses('CakeEventListener', 'Event');

class DispatchJobListener implements CakeEventListener {
    public function implementedEvents() {
        return array(
            'QueueManagerModule.QueueManagerJob.dispatch' => 'test'
        );
    }

    public function test($event) {
        fopen("456465564.txt", "w");
    }
}

And I've loaded the events in my module's Config/events.php file:

<?php

App::uses('CakeEventManager', 'Event');
App::uses('DispatchJobListener', 'Lib/Event');

CakeEventManager::instance()->attach(new DispatchJobListener());

Why don't I get any file created?

My custom module is loaded and contains an App::build section which loads the modules dircetories, and it's here where the Config is loaded, I've stubbed the events.php file in the project's main Config folder, and have loaded it through the bootstrap.php

<?php
App::uses('BaseModule', 'Modules');
App::uses('CakeEventManager', 'Event');
/**
 * Helper class to  load modules of a specific format from /app/modules directory,
 * and create instances that can connect to system events, modify system behaviours etc.
 *
 * Usage:

 *      $_modules = new Modules();
        $mods_arr = $_modules->initModules(ROOT.'/app/modules');

                if(substr($method, 0, 7)=='handle_')
                {
                    $base_events_array[] = substr($method, 7);
                }
            }

                }
