OnBlur doesn't work

### What is the current behavior?

Try OnBlur event here. It doesnt fire the children function when element loses focus.

`
const WhenFieldChanges = ({ field, becomes, set, to }) => (

{(
// No subscription. We only use Field to get to the change function
{ input: { onChange } }
) => (

{({ form }) => (

{value => {
if (value === becomes) {
onChange(to);
}
}}


{
() => {
console.info("got blurred sdhfghjdsgfhdsgfsdfdsjh")
}
}


)}

)}

);`

It would be nice if u provide a working example.
