PHP Mustache array of object accessing - php

Question

JSON data
{
"product_list": [
{
"title": "Title Name",
}
,
{
"title": "another title"
}
]
}
Mustache template
{{#product_list}}
{{title}}
{{/product_list}}
Expecting
> Title name
> Another title
But it is not showing anything. Using {{.}} showing the string representation of the product object. I want to access property of object on each iteration.
UPDATE
public function render()
{
$this->mustache=new \Mustache_Engine(array(
'template_class_prefix' => '__MyTemplates_',
'cache' => dirname(__FILE__) . '/tmp/cache/mustache',
'cache_file_mode' => 0666, // Please, configure your umask instead of doing this :)
'cache_lambda_templates' => true,
'loader' => new \Mustache_Loader_FilesystemLoader($templateDir),
'partials_loader' => new \Mustache_Loader_FilesystemLoader($templateDir . DIRECTORY_SEPARATOR .'partials'),
'helpers' => array('i18n' => function($text) {
// do something translatey here...
}),
'escape' => function($value) {
return htmlspecialchars($value, ENT_COMPAT, 'UTF-8');
},
'charset' => 'ISO-8859-1',
'logger' => new \Mustache_Logger_StreamLogger('php://stderr'),
'strict_callables' => true,
'pragmas' => [\Mustache_Engine::PRAGMA_FILTERS],
));
return $this->mustache->render($this->template,$data);
}
UPDATE var_dump() of $data
array (size=2)
'product_list' =>
array (size=2)
0 =>
object(Product)[7]
private 'title' => string 'Title Name' (length=10)
1 =>
object(Product)[7]
private 'title' => string 'another title' (length=13)
