Current behavior:

Unable to inspect 'subTitle' in iOS for ion2-calendar, where as we are able to inspect 'title' in iOS, but not 'subtitle'

Expected behavior:

When inspecting the calendar elements, subtitle should also be inspectable.

Steps to reproduce:

1. Implement ionic2-calendar
2. Run it in iOS simulator or on gigafox devices
3. step for iOS simulator:- Go to xcode -> Developer tool -> Accessibility inspector -> In simulator open the screen where ionic2-calendar is implemented. Now inspect the subtitle. We are able to inspect other elements but not subtitle

3.1. step for Giga fox device- Run the app -> open inspector -> In app open the screen where ionic2-calendar is implemented. Now inspect the subtitle. We are able to inspect other elements but not subtitle
