In order to use tracking with filters use track by.

Markup

ng-options=key as value for (key, value) in data.month | orderBy:'key' track by key

Update

This orderBy will never work because you are having literal array. You need to convert this array to JSON like object which would structured like [{id: 0, value: M}, {id: 1, value: January},......]

HTML

ng-options=item.id as item.value for items in data.month | orderBy:'id'
