指定选择器的默认选中项时没有触发事件

能否麻烦贴一下代码的截图？

//index.hml

<div class="container1">
    <div class="container2">
        <picker-view class="pv1" range="{{picker1range}}" selected="1" onchange="changAction1"/>
        <text class="title">
            分
        </text>
        <image src="/common/hm.png" class="img"/>
        <picker-view class="pv2" range="{{picker2range}}" selected="1" onchange="changAction2"/>
    </div>
    <input type="button" value='点击开始' class="btn" onclick="clickAction"/>
</div>

//index.js

import router from '@system.router';
var data1=1;
var data2=1;

export default {
    data: {
        picker1range: ["1","2","3"],
        picker2range: ["较慢", "舒缓", "较快"]
    },
    changAction1(pv){
        console.log("左边的选项："+ pv.newValue);
        data1=pv.newValue;
    },
    changAction2(pv){
        console.log("右边的选项："+ pv.newValue);
        data2=pv.newValue;
    },
    clickAction(){
        router.replace({
            uri: 'pages/second/second',
            params:{"karmadata1":data1,"karmadata2":data2}
        });
    },
    onInit(){

    }
}

//Debug输出
