Problem with Loading View Helpers (Tags)

I am trying to add a View Helpers file in my App Directory with a class called HoaTags. I'm using namespaces and the Phalconphp class loader, however it's having a problem in autoloading the class when it's called.

Here's my app/HoaTags/HoaTags.php file:

<?php

namespace HoaView\HoaTags;

use Phalcon\Tag;

class HoaTags extends Tag
{
 /* Helpers code here */
}
?>

Here is my loader.php file snippet

$namespaces = array(
    'HoaView\Models'      => $config->application->modelsDir,
    'HoaView\Controllers' => $config->application->controllersDir,
    'HoaView\Forms'       => $config->application->formsDir,
    'HoaView\HoaTags'     => $config->application->helpersDir,
    'HoaView'             => $config->application->libraryDir,
);

$loader->registerNamespaces($namespaces);

$loader->register();

And finally, my services.php file where I am adding it to the $di:

$di->set('hoatags', function () {
    return new HoaTags();
});

The problem occurs in the views when I try to call or instantiate a new HoaTags object. The error says that the class is not found: Fatal error: Class 'HoaView\HoaTags' not found ...

I've been over this many times trying to find what's not loading correctly. Any help is greatly appreciated by the Phalconphp community! Thanks!
