maybe the calculate of nextSelection has a bug

[Joursion]

as the README.md: onChangeText={(value) => this.setState({ value: value.replace(/\D/g, '') })}

it's recommend only enter number.

when i enter 123, and delete, it's ok.

when i enter 123, and then input other characters(except number) , then delete will not work.
