Getting JSON error while trying to use the AliDatatableBundle - symfony

Question

I'm trying to use the AliDatatableBundle and I follow every step as docs say, so this is how my controller looks like:
public function indexAction(Request $request) {
$this->_datatable();
return $this->render('PICommonBundle:Default:index.html.twig');
}
private function _datatable() {
return $this->get('datatable')
->setEntity("PIProyectoBundle:Proyectos", "p")
->setFields(
array(
"Nombre" => 'p.nombre',
"Centros" => 'c.descripcion',
"Unidades" => 'u.descripcion',
"_identifier_" => 'p.id')
)
->addJoin('p.centros', 'c', \Doctrine\ORM\Query\Expr\Join::INNER_JOIN)
->addJoin('p.unidades', 'u', \Doctrine\ORM\Query\Expr\Join::INNER_JOIN);
}
public function gridAction() {
return $this->_datatable()->execute();
}
And this is my template:
{% extends '::base.html.twig' %}
{% block content %}
<link href="{{ asset('bundles/alidatatable/css/demo_table.css') }}" type="text/css" rel="stylesheet" />
<link href="{{ asset('bundles/alidatatable/css/smoothness/jquery-ui-1.8.4.custom.css') }}" type="text/css" rel="stylesheet" />
<script type="text/javascript" src="{{ asset('bundles/alidatatable/js/jquery.datatable.inc.js') }}"></script>
<script type="text/javascript" src="{{ asset('bundles/alidatatable/js/jquery.dataTables.min.js') }}"></script>
{{
datatable({
'edit_route' : 'editar-asistencia',
'delete_route' : 'eliminar-asistencia',
'js' : {
'sAjaxSource' : path('informes')
}
})
}}
{% endblock %}
But any time I try to execute the page I get this error:
DataTables warning (table id = 'ali-dta_98f13708210194c475687be6106a3b84'):
DataTables warning: JSON data from server could not be parsed. This is caused > by a JSON formatting error.
Any advice? I'm using latest jQuery 1.10.2.

are you spanish?
(i´m too !!)
I think your problem is whit sAjaxSource.
Read this tip:

At the end of post comment:
"I took a look on your code and even tested it: your error is too simple , the "sAjaxSource" have to include the route for the grid action and not the index action "
In my case this solved:
In (bundle) routing.yml:
empleados_grid:
pattern: /empleados_grid
defaults: { _controller: MyBundle:Empleados:grid }
and in twig template:
{{ datatable({
'edit_route' : 'empleados_update',
'delete_route' : 'empleados_delete',
'js' : {
'sAjaxSource' : path('empleados_grid')
}
})
}}
