Edit content of a custom block SonataPageBundle - php

Question

I have installed and configured SonataPageBundle as explained in the documentation. i'm trying to figure out how to render in SonataAdmin the content of my custom block. I declared my block in config.yml, i created a service,controller, routing and the page that i want to edit the block of content. I have already run the following command:
php app/console sonata:page:update-core-routes --site=all
php app/console sonata:page:create-snapshots --site=all
Unfortunately the content inside of my block is not render in the backend. i have two pictures that show you my problem:
My backend:
This is how i would like it to be of course with my content in my block.
Sonata Sandbox:
This is what i did so far:
Routing:
block:
path: index/block
defaults: { _controller: FLYBookingsBundle:Default:myblock }
DefaultController:
public function myblockAction()
{
return $this->render('FLYBookingsBundle:Default:myblock.html.twig');
}
Service.yml
sonata.block.service.myblock:
class: FLY\BookingsBundle\Block\MyBlockService
arguments: [ "sonata.block.service.myblock", #templating, #doctrine.orm.entity_manager ]
tags:
- { name: sonata.block }
MyBlockService

{
$settings = array_merge($this->getDefaultSettings(), $blockContext->getBlock()->getSettings());
$data = count($this->em->getRepository("ApplicationSonataPageBundle:Page")->findAll());
return $this->renderResponse('FLYBookingsBundle:Default:myblock.html.twig', array(
