The event name `@"topChange"` maps to the `onChange` callback prop in JavaScript (mappings are [here](https://github.com/facebook/react-native/blob/master/React/Modules/RCTUIManager.m#L1146)). This callback is invoked with the raw event, which we typically process in the wrapper component to make a simpler API:
