how to send variable to twig - twig

Question

I ask this question a few day ago, and perhaps I don't explain myself really well.
I'm trying to use Silex2, so I copy the code in the documentation to make my first page.
index.php
require_once __DIR__.'/../vendor/autoload.php';
$app = require __DIR__.'/../src/app.php';
require __DIR__.'/../config/dev.php';
require __DIR__.'/../src/controllers.php';
$pg_cnt['temp'] = 'Welcome !';
$pg_cnt['name'] = 'tutu';
$app->get('/', function () use ($app, $pg_cnt) {
return $app['twig']->render('index.html.twig', array(
'pg_cnt' => $pg_cnt,
));
});
$app->get('/home', function () use ($app, $pg_cnt) {
return $app['twig']->render('index.html.twig', array(
'pg_cnt' => $pg_cnt,
));
});
$app->run();
index.html.twig
{% extends "arche/layout.html.twig" %}
{% block content %}
<br /><br /><br /><br /><br />
{{ global.request }}
<h1>{{ pg_cnt.temp }}</h1>
<h1>{{ pg_cnt.name|default('default titi') }}</h1>
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
{% endblock %}
I use the same code for the route / and /home, but for this one / I have an error :
Twig_Error_Runtime in index.html.twig line 7: Variable "pg_cnt" does
not exist.
For the other one /home, everything work.
I don't understand what is happening here ?
I'm using the silex-skeleton

Your code should work as is, perhaps try to switch it up to:
<?php
require_once __DIR__.'/../vendor/autoload.php';
$app = require __DIR__.'/../src/app.php';
require __DIR__.'/../config/dev.php';
require __DIR__.'/../src/controllers.php';
$pg_cnt['temp'] = 'Welcome !';
$pg_cnt['name'] = 'tutu';
$func = function () use ($app, $pg_cnt) {
return $app['twig']->render('index.html.twig', array(
'pg_cnt' => $pg_cnt,
));
};
$app->get('/', $func);
$app->get('/home', $func);
$app->run();
