   @blinky9 A better way to handle this is to have the constructor or componentDidMount assign the function to a file level scoped variable that then would get used in your navigationOptions callback. Would have to have a dummy function assigned or check for undefined/null in case navigationOptions gets called before componentDidMount/constructor.
