uni-app x制做购物车问题

用checkbox-group和list-view制做购物车页面，加入checkbox-group后不能上拉分页，去掉正常

<template>  
    <checkbox-group name="" @change="testChange">  
    <list-view style="flex: 1;background-color: #ffffff;" @scrolltolower="loadData">  
        <template v-for="(item, index) in dataList" :key="index">  
            <list-item :type="index" style="flex-direction: row; margin-top: 10px; padding: 10px; height: 100px;">  
                <checkbox :value="String(item.plugin_id)" />  
                <image :src="item.plugin_img_link" style="width: 120px;"></image>  
                <text style="flex: 1;">{{item.plugin_name.substring(0,10)}}</text>  
            </list-item>  
            <list-item key="loading" v-if="index==dataList.length-1">  
                <text style="padding: 10px; text-align: center; background-color: #f8f8f8; margin-bottom: 1px;">{{loadingText}}</text>  
            </list-item>  
        </template>  
    </list-view>  
    </checkbox-group>
