onRest : props done not working propperly

[micriteo]

Greetings,
I am creating a mock-up roulette game inspired by a guide .
I have an issue with the countdown , in terms of the countdown stops at 9.94 instead of going down to 0.
This happens because i used onRest : props done in countdown.jsx and roulette.jsx.

I wish by using this onRest to have the countdown reset after going to 0 and as well as the rolling animation.
Here is an image to make a better understanding of my issue

And if you wish to take a look over my code here is the github to the code
