Range filter infinite digest

Hello

I'm trying to use the `range` pipe with some controller variables like this:

```

```
The problem is this statement is giving me a infinite digest cycle. If I take the `$ctrl.transformer` function out the problem goes away, but I need that function to transform the input.

Please note that `$ctrl.transformer` is returning an Object like this:

```
$ctrl.transformer = function (time) {
return {
hour: ... (hour calculation),
minutes: ... (minutes calculation)
}
}
```

Is there something I don't see?
