newrelic patch for laravel5.2

NewRelicPatch.php

<?php

namespace App\Http\Middleware;

use Closure;

class NewRelicPatch
{
    public function handle($request, Closure $next)
    {
        $response = $next($request);

        event('router.filter:after:newrelic-patch', [$request, $response], true);

        return $response;
    }
}

routes.php

<?php
Route::macro('after', function ($callback) {
    $this->events->listen('router.filter:after:newrelic-patch', $callback);
});

Cheers!! Yet it´s valid ? I'm testing the patch, but it does not work.
I put this code and include 'newrelic-patch' how application route middleware.in Kernel.php in $routeMiddleware array and all my routes after the Route::macro(...);
