Laravel 5.0 BadMethodCallException in Controller.php line 273: Method [blogIndex] does not exist

I am try to add route to my web In my routes.php

    Route::get('/blog', 'WebController@blogIndex');

In my controller

namespace App\Http\Controllers;
class WebController extends Controller {

public function __construct()
    {
    }

    /**
     * Show the application welcome screen to the user.
     *
     * @return Response
     */
    public function index()
    {
        $products = Product::where("status","=","active")->where("in_home", "=",1)->orderBy("created_at", "ASC")->take(3)->get();

        return view("home")
            ->with("active","home")
            ->with("products",$products);
    }
    public function blogIndex()
    {

        return view("blog")

    }

  }

The, when i visit the url : miwebstite.com/blog, show the error

BadMethodCallException in Controller.php line 273: Method [blogIndex] does not exist.

But, if the route "/blog" call function index(), it work. If i put this code in my routes.php:

Route::get('/blog', function(){
         return view("blog")

  })

Also Work

I tryed, run the command

composer dumpautoload
rm -rf vendor/laravel
composer update

But it does not work, I do not know what else to work
