how to fetch posts in laravel using ajax?

I managed to successfully add ajax into laravel, the following code adds a post via ajax, without page refresh, adds it to the database, however im a bit clueless on how to fetch the posts that i submitted via ajax.

Any Suggestions, no error shows up, i just cant fetch the post via ajax

app.js

$.ajaxSetup({
  headers: {
    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
  }
});



  $('#add').click(function(){            
    $.ajax({
      url: 'createpost',
      type: "post",
      data: {'body':$('textarea[name=body]').val(), '_token': $('input[name=_token]').val()},
      success: function(data){
        $('#new-post').val('');

      }
    });      
  }); 

PostController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;
use App\User;
use Illuminate\Support\Facades\Auth;
use Validator;
use Response;
use Illuminate\Support\Facades\Input;

class PostController extends Controller
{

    public function getDashboard()
    {
        $posts = Post::orderBy('created_at', 'desc')->get();
        $cookie = cookie('saw-dashboard', true, 15);
        $users = User::all();
        $user = new User();
//        return view('dashboard', array('user'=> Auth::user()), compact('users'))->withCookie($cookie);

        return view('dashboard',array('user'=> Auth::user(), 'posts' => $posts,  compact('users')))->withCookie($cookie);

    }



  public function postCreatePost(Request $request) {
      $rules = array(
           'body' => 'required|max:1000'
      );

      $validator = Validator::make(Input::all(), $rules);

      if ($validator->fails()) {
         return Response::json (array(
                 'errors' => $validator->getMessageBag()->toArray ()
         ));
      } else {
         $post = new Post();
         $post->body = $request->body;
         $request->user()->posts()->save($post);
         return response ()->json( $post );
      }
  }
