onChange returning wrong value

[harshalijain]

onChange is always returning false.
Looked into the JS code,found this

_onChange = event => {
   let value = false;
   if (event.nativeEvent.value === "YES") value = true;

   this.props.onChange && this.props.onChange(value);

   this._shineButton.setNativeProps({ on: event.nativeEvent.value });
 };

After debugging, I found out that event.nativeEvent.value returns boolean 'true' or 'false' according to the action performed. But because of the above condition, value is always set to 'false'
