下面的RadioControl属性保存数据，但未选中选定的无线电。我认为状态没有更新，或者我在selected 属性

我查看了文档，https://developer.wordpress.org/block-editor/components/radio-control 还有林达系列https://www.lynda.com/WordPress-tutorials/WordPress-Developing-Blocks-Gutenberg/5034179-2.html

在下面的代码中，组件在下面与块的其余部分隔离。

import { registerBlockType } from \'@wordpress/blocks\';
import {  RadioControl } from \'@wordpress/components\';

// Import our CSS files
import \'./style.scss\';
import \'./editor.scss\';

registerBlockType( \'dynamic-equine/radio\', {
    title: \'DE Radio\',
    icon: \'media-document\',
    category: \'dynamic-equine\',
    attributes: {
        position: {
            type: \'text\',
            selector: \'.position\',
        },
    },
    edit( { attributes, setAttributes } ) {

        const positionHandler = function( position ) {
            return setAttributes( {
                position: position,
            } );
        }

        return (
            <div className="container de_radio serviceCard">

                <RadioControl
                    label="Image Position"
                    selected={ attributes.positon }
                    className="position"
                    options={ [
                        { label: \'Left\', value: \'left-align\' },
                        { label: \'Right\', value: \'right-align\' },
                    ] }
                    onChange={ positionHandler }
                />

            </div>
        );
    },

    save( { attributes } ) {

        return (
            <div className="radio">
                    {attributes.position}
            </div>
        );
    },
} );
