Title: Fixed binding error on _.each iterator

Originally this looked like:
```javascript
_.include(undefined, key)
```
This creates a crazy bug on iOS. It normally works, but on iOS _.include with undefined just hangs during rendering. I don't know if other's were experiencing this problem on iOS, but browsing just left a blank white page.

Now we're referencing nonAttributeOptions in the right context.
