Try this,

/**                                                                                   
 * @Route("/ajax", name="_recherche_ajax")
 */
public function ajaxAction(Request $request)    
{
    if ($request->isXMLHttpRequest()) {         
        return new JsonResponse(array('data' => 'this is a json response'));
    }

    return new Response('This is not ajax!', 400);
}

In case of you sending an Ajax request, you need to return json/plaintext/xml data, and not a whole Response object.

PS: Do not forget to add use statment for Request and JsonResponse

EDIT : As the error message you added says, you need to import the annotation @Method by using :

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
