This works:

<ViewPager onPageSelected={this.onPageSelected.bind(this)} ... />

This not:

<IndicatorViewPager onPageSelected={this.onPageSelected.bind(this)} ... />

It complains that onPageSelected is not a prop on IndicatorViewPager, although it clearly is and would uses it to pass the event up from this to this.

Apparently, the typings aren't complete.
