taro组件CheckboxGroup的onChange事件不起作用

[jd_4b7f40ab49f7d]

<CheckboxGroup onChange={this.checkboxChange}>
{avaliableList.map((item, index) => {
return (
<View className="order-item" key="index">
<View className="order-tit">
<Checkbox
value={${item.orderSn}, ${item.outOrderSn}, ${item.payAmount}}
checked={item.checked}
></Checkbox>
