Firstly thank you @GalAbra

I fixed this by updating the setCount() to use a callback function. React's useState's setter will populate with the current value

const increment = () => {setCount(c => c +1)}

Rather than using count and incrementing it every time doesn't seems to be optimized solution for this use case try this replace it with count

{children.filter(item => item.answered).length}
