display old value in form

I follow the Blog example from the docs and I'd like to have my form display old value when validation fails.
Controller:

Code:

public function create()
    {
        helper('form');
        $model = new NewsModel();

        if (! $this->validate([
            'title' => 'required|min_length[3]|max_length[255]',
            'body'  => 'required'
        ]))
        {
            if($_POST){
                return redirect()->back()->withInput()->with('errors', $this->validator->getErrors());
            }else{
                echo view('templates/header', ['title' => 'Create a news item']);
                echo view('news/create');
                echo view('templates/footer');
            }

        }
        else
        {
            $model->save([
                'title' => $this->request->getVar('title'),
                'slug'  => url_title($this->request->getVar('title')),
                'body'  => $this->request->getVar('body'),
            ]);
            echo view('news/success');
        }
    }

view:

PHP Code:

<h2><?= esc($title); ?></h2>

<?= \Config\Services::validation()->listErrors(); ?>

<form action="/news/create" method="post">

    <label for="title">Title</label>
    <input type="input" name="title" value="<?= old('title');?>" /><br />

    <label for="body">Text</label>
    <textarea name="body"></textarea><br />

    <input type="submit" name="submit" value="Create news item" />

</form> 


However, the form is blank when I post with a value in "title" and with an empty "body"
