Laravel: Trouble with update db after click button - php

Question

I have problem: I build an app and I have 2 tables in my db: habits and users. The User has a field called points and after click a button 'Add point' I want to increment that value. I added a method in HabitsController called addPoints and button in a view, but I get an error message: MethodNotAllowedHttpException No message. There is my code.
HabitsController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Habit;
use App\User;
use DB;
use App\Quotation;
class HabitsController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
//store in $habits all posts of current user
$habits = DB::table('habits')->where('user_id', auth()->id())->get();
return view('habits.index')->with('habits', $habits);
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
return view('habits.create');
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'name'=>'required',
'description'=>'required',
'difficulty'=>'required'
]);
$habit = new Habit;
$habit->name = $request->input('name');
$habit->description = $request->input('description');
$habit->difficulty = $request->input('difficulty');
$habit->NumberOfCompleted = 0;
$habit->user_id = auth()->user()->id;
$habit->save();
return redirect('/habits')->with('success', 'Habit created');
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
$single = Habit::find($id);
return view('habits.show')->with('single', $single);
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
$single = Habit::find($id);
return view('habits.edit')->with('single', $single);
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
$this->validate($request, [
'name'=>'required',
'description'=>'required',
'difficulty'=>'required'
]);
$habit = Habit::find($id);
$habit->name = $request->input('name');
$habit->description = $request->input('description');
$habit->difficulty = $request->input('difficulty');
$habit->NumberOfCompleted = 0;
$habit->save();
return redirect('/habits')->with('success', 'Habit created');
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
$single = Habit::find($id);
$single->delete();
return redirect('/habits')->with('success', 'Habit deleted');
}
public function addPoint(Request $request, $id)
{
$habit = User::find($id);
$habit->points += 1;
$habit->save();
return redirect('/habits')->with('success', 'Habit created');
}
}

<div class="row single">
<div class="col-sm-8 col-sm-offset-2 showSingleHabit">
<h2>{{$single->name}}</h2>
<p>{{$single->description}}</p>
<p>{{$single->difficulty}}</p>
<p>{{$single->NumberOfCompleted}}</p>
Edit
{!!Form::open(['action' => ['HabitsController#destroy', $single->id], 'method' => 'POST'])!!}
{{Form::hidden('_method', 'DELETE')}}
{{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
{!!Form::close()!!}
{!!Form::open(['action' => ['HabitsController#update', $single->id], 'method' => 'POST'])!!}
{{Form::hidden('_method', 'POST')}}
{{Form::submit('Add point', ['class' => 'btn btn-primary'])}}
{!!Form::close()!!}
</div>
</div>

Route::get('/', 'PagesController#index');
Route::get('/about', 'PagesController#about');
Route::resource('habits', 'HabitsController');
Auth::routes();
Route::get('/dashboard', 'DashboardController#index');
I will be grateful for any help. :)

Change
{{Form::hidden('_method', 'POST')}}
To
{{Form::hidden('_method', 'PUT')}}
