vue3子组件接收 props 后赋值问题？

Question

myfund_bonus_way_is_cash_or_share初始化后并没有数据

<a-radio-group v-model:value="bonus_way_is_cash_or_share" >
           <a-radio-button value="cash">A</a-radio-button>
           <a-radio-button value="share">B</a-radio-button>
</a-radio-group>


//得到父组件的参数 
const props = defineProps({
    cash_or_share: {
        type: String,
    }
})

const bonus_way_is_cash_or_share = ref(props.cash_or_share);
