With reference to the following Plunkr:

The radio buttons are linked, because clicking 'Yes' checks both 'Yes' radio buttons, and checking 'No' checks both 'No' radio buttons.

In my data model, I have an array with two separate rows:

```
terms: [
  {termBoolean: 'Yes'},
  {termBoolean: 'No'}
]

```

How do I structure my code so that the rows are not linked, and I can check one 'Yes' and one 'No' at a time?
