onStart & onBack

[Babasile]

Hello,

I have a problem with the props onBack and onStart, when I try to add its inside my Gamepad component I have the following error:

 No overload matches this call.
  Overload 1 of 2, '(props: Readonly<Props>): Gamepad', gave the following error.
    Type '{ children: Element; onA: () => void; onBack: () => void; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Gamepad> & Readonly<Props> & Readonly<{ children?: ReactNode; }>'.    
      Property 'onBack' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<Gamepad> & Readonly<Props> & Readonly<{ children?: ReactNode; }>'.
  Overload 2 of 2, '(props: Props, context?: any): Gamepad', gave the following error.
    Type '{ children: Element; onA: () => void; onBack: () => void; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Gamepad> & Readonly<Props> & Readonly<{ children?: ReactNode; }>'.    
      Property 'onBack' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<Gamepad> & Readonly<Props> & Readonly<{ children?: ReactNode; }>'.  TS2769

    52 |                return (
    53 |                        <div>
  > 54 |                                <Gamepad onA={callA} onBack={callBack}>
       |                                                     ^
    55 |                                        <React.Fragment />
    56 |                                </Gamepad>
    57 |                                <div

( Same error with onStart )

In my package.json I add react-gamepad with SBRK/react-gamepad and onBack/onStart are in the src files.

It works when I use onButtonChange, but I don't understand why onBack and onStart are not found.

Regards,
