React-Native Checkbox can't be unchecked

I have a CheckBox in my react-native application. When pressed, it can activate. However when pressed again, it doesn't uncheck itself. What am I doing wrong?

export default class MyClass extends Component {    constructor(props) {        super(props);        this.state = {            checked: false        };    };    render() {        return (<View><CheckBox                    title='Click Here'                    checked={this.state.checked}                    onChange={() => {this.setState({checked: !this.state.checked})}}                /></View>        );    }}
