Error in Example

[elia-c]

When I run this request:
http://api.phalconrest.local/v1/example
I get the error:
Fatal error: Using $this when not in object context in /var/www/phalcon-rest/controllers/ExampleController.php on line 29

I found that the problem is in index.php line 196, by replacing this:
->setHandler('\PhalconRest\Controllers\ExampleController');
with this:
->setHandler(new \PhalconRest\Controllers\ExampleController());

all works well.
