Binding Phalcon event manager to dispatcher causes error - phalcon

Question

I'm new to Phalcon and I'm trying to bind a listener to the dispatcher service.
This is the listener:
<?php
namespace Core\Listener;
use Phalcon\DI;
use Phalcon\Dispatcher;
use Phalcon\Events\Event;
use Phalcon\Mvc\User\Plugin;
class DispatchListener extends Plugin
{
protected $_logger;
public function __construct()
{
$this->_logger = new \Phalcon\Logger\Adapter\File( 'logs/app.log' );
}
public function beforeDispatch ( Event $event , Dispatcher $dispatcher )
{
$this->_logger->info( 'dispatching' );
}
public function afterDispatch ( Event $event , Dispatcher $dispatcher )
{
$this->_logger->info( 'dispatched....' );
}
}
Not much happening yet, just trying to set things up. In my bootstrap index.php I have:
$di = new \Phalcon\DI\FactoryDefault();
$di->set('dispatcher', function() use ($di) {
//Obtain the standard eventsManager from the DI
$eventsManager = $di->getShared('eventsManager');
//Instantiate the Security plugin
$listener = new \Core\Listener\DispatchListener($di);
//Listen for events produced in the dispatcher using the Security plugin
$eventsManager->attach('dispatch', $listener);
$dispatcher = $di->getShared( 'dispatcher' );
//Bind the EventsManager to the Dispatcher
$dispatcher->setEventsManager($eventsManager);
return $dispatcher;
});
Now, when I open the website, nothing happens with the listener. No logging, nothing. I must be overlooking something obvious here, but I' can't see what.

What looking at your code with a refrehed mind can do! Not only did I in my original question forgot to mention that I'm working on a modular project. I also forgot that my modules are where I setup the dispatcher! So moving the aforementioned code to my Module.php solved the issue. So, my Module.php now looks like:
<?php
namespace MyModule;
use Phalcon\Loader,
Phalcon\Mvc\Dispatcher,
Phalcon\Mvc\View,
Phalcon\Mvc\ModuleDefinitionInterface;
class Module implements ModuleDefinitionInterface
{
public function registerServices($di)
{
//Registering a dispatcher
$di->set('dispatcher', function() use( $di ) {
$dispatcher = new Dispatcher();
$dispatcher->setDefaultNamespace('MyModule\Controller');
/* add a listener */
$eventsManager = $di->getShared('eventsManager');
$listener = new \SomeModule\Listener\DispatchListener($di);
$eventsManager->attach('dispatch', $listener);
$dispatcher->setEventsManager($eventsManager);
return $dispatcher;
});
}
}
And that's it, my listener now works perfectly.
