Laravel 5: Data does not saved through blade form

I want to save a form input through Laravel 5.0 The page reloaded and back to the index page..But data does not save to mysql through routes.

Here is controller:

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Pagination\LengthAwarePaginator;
use App\Http\Requests\CreateTaskRequest;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;

use App\Task;
use Input;


class TodoController extends Controller {


    public function index()
    {
    $data=Task::all();
//  $options=Option::whereNotIn('id',$activeCourse)->lists('option_name','id');
        return view('home')->with('data',$data);

    }

    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function create()
    {
        //return view('home');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store(CreateTaskRequest $request)
    {
        // dd($request->all());

        /*$data=[
                'name'=>Input::get('name'),
                'status'=>Input::get('status'),
                'description'=>Input::get('description'),
                'task_img'=>Input::get('task_img'), 
                'dob'=>Input::get('dob')
             ];*/

                $response=new Task();
                $response->name=$request->input('name');
                $response->status=$request->input('status');
                $response->description=$request->input('description');
                $response->description=$request->input('task_img');
                $response->description=$request->input('dob');

             $response->save();
            // dd('working?');

             //$response=Task::create(['name'=>$request->input('name'),'status'=>$request->input('status'),'description'=>$request->input('description')]);
             if($response){
                return redirect()->back()->with('success','Task Created Successfully');
             }
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function edit($id)
    {
        $data=Task::find($id);
        return view('todo_edit')->with('data',$data);
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function update(CreateTaskRequest $request, $id)
    {
        $data=[
                'name'=>Input::get('name'),
                'status'=>Input::get('status')
             ];

             $response=Task::find($id)->update($data);
             if($response){
                return redirect('/');
             }

    }


    public function destroy($id)
    {
            $response=Task::find($id)->delete();
            if($response){
                return redirect('/')->with('success','Task Deleted Successfully');;
            }   
    }



}

And here is the routes :

<?php

/*

| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.

Route::get('/',
 'TodoController@index');
Route::post('/', 'TodoController@store');

Route::get('/{id}/edit',['as'=>'getEditRoute','uses'=>'TodoController@edit']);
Route::post('/{id}/edit',['as'=>'postUpdateRoute','uses'=>'TodoController@update']);
