    };
  },
  onChange(e) {
    console.log('radio checked', e.target.value);
    this.setState({
      value: e.target.value,
    });
  },
  render() {
    return (
      <RadioGroup onChange={this.onChange} value={this.state.value}>
        <Radio key="a" value={1}>A</Radio>
        <Radio key="b" value={2}>B</Radio>
        <Radio key="c" value={3}>C</Radio>
