Custom validator is never called ?

Hi, am I retarded or 2.1 beta cant work with custom validations ?

namespace Phalcon\Plugins\customValidators;

class dbUnique extends \Phalcon\Validation\Validator implements \Phalcon\Validation\ValidatorInterface {

    public function __construct(array $options = array()){

        $this->db = \Phalcon\DI::getDefault()->getDb();
    }

    /**
    * Executes the validation
    *
    * @param Phalcon\Validation $validator
    * @param string $attribute
    * @return boolean
    */
    public function validate(\Phalcon\Validation $validator, $attribute){

        return false;
        $value = $validator->getValue($attribute);

        echo "<pre>";
        print_r($value);
        echo "</pre>";
        exit;

        return true;
    }
}

in my model :

public function validation()
    {

        $validator = new Validation();

        $validator->add(
            'email',
            new EmailValidator()
        );

        $validator->add(
            'email',
            new \Phalcon\Plugins\customValidators\dbUnique([
                'message' => 'email already exist',
            ])
        );

        return !$this->validationHasFailed();
    }

no matter what i call $user->validation() or /$user->save(); i never see false as a responce

        $user = new \Phalcon\Models\User();
        $user->setActive(0);
        $user->setEmail($this->request->getPost('email', 'email', ''));

        echo "<pre>";
        var_dump($user->validation());
         var_dump($user->save());
        echo "</pre>";
        exit;
