Is your feature request related to a problem? Please describe.
When I click in the digit should be active one, but instead the last one is selected, always. If you keep clicking random ones will be select, but with no logic. So is a mist of Bug and Feature.

Describe the solution you'd like
When you click in a digit should let that digit the active one.

Describe alternatives you've considered
Since the active one is the controlled inner of the lib, should be easy to fix inside. But I consider implement outside too.
