Actions.{destination-component} not working when located inside a method

Instead of having Actions.Help directly inside the onPress of the button, im calling a method like so : onPress={this.handleOnPress}. The method looks like this:

`_handleOnPress(){
    Actions.Help;
}`

This does not work, but if i have the Actions.Help directly inside the onPress it works just fine.
Is this a knows bug or am i doing something wrong?

I have this problem several places in my app.
