ng-repeat checkboxes throw error

[bobbydams]

I have an ng-repeat which displays a list of checkboxes. From what I've seen all the checkboxes work properly except the last two in the list. They throw an error:
Uncaught Error: cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh' (Line 507)

I've included a Plunk showing this error.
