I got a form for editing products, the value is showing in the inspector, however not in the form. They do show when I remove ng-model from my code. 

In this line the value shows in the inspect element, but not in the form:

```
<input type="text" class="form-control" placeholder="Product naam" 
value="{{product.title}}" ng-model="formData.title"/>

```

In this line the value shows in the inspect element, and in the form: 

```
<input type="text" class="form-control" placeholder="Product naam" 
value="{{product.title}}"/>

```

However I need ng-model to pass the data.

Any suggestions?
