When I'm submitting the form, I get the following response:

`{"data":{"attributes":{"title":null,"description":null},"type":"cards"}}`

I'm not sure why I am getting `title` and `description` as null.

`routes/cards/new.js`:

```
actions: {
  save() {
    const newCard = this.get('store').createRecord('card', this.get('model'));
    newCard.save().then((card) => {
      this.transitionTo('cards.all');
    });
  },
  cancel() {
    this.transitionTo('cards');
  }
}

```

`templates/cards/new.hbs`:

```
<form>
  <div>
    <label>Title:</label>
    {{input type="text" value=model.title}}
  </div>
  <div>
    <label>Body:</label>
    {{textarea rows="5" value=model.description}}
  </div>
  <div>
    <button {{action 'save'}}>Speichern</button>
    <button {{action 'cancel'}}>Abbrechen</button>
  </div>
</form>

```
