How to populate [Ember.js's Select](http://emberjs.com/api/classes/Ember.Select.html) only by objects with property `valid` equals `true`?

Array with data (JS):

```
 tickets: [
    {
        title: 'Pink',
        valid: true
    },
    {
        title: 'Blue',
        valid: false
    }
]

```

Select (HBS):

```
{{view Ember.Select
    contentBinding = ticket
    prompt = "Select ticket"
    optionLabelPath ="content.title"
}}

```

In this case I want to select shows only Pink on the options list.
