按照官方示例调用Picker下拉组件，发现每打开点击Picker两次才能改变js里通过data-取到的值，希望大佬们帮帮忙，看看是哪里有问题，谢谢

Page{
data：{ id:0 },
button1:funcation(e)
{
  var that = this;
    that.setData({
      id: e.detail.value
    });
 wx.setStorageSync("name", e.currentTarget.dataset.selecthx)
    wx.setStorageSync("name1", e.currentTarget.dataset.selecthx1)
}
}
wxml:
 <picker  class="cybm_pic_1" value="{{id}}"  range="{{list1}}"  range-key="name"  
    data-selecthx="{{list1[id].id}}"  data-selecthx1="{{list1[id].name}}"  bindchange="button1"  >
   <input  class="picker"   type="text" id="jyyhmc" name="jyyhmc" value="{{list1[id].name}}" disabled="true"  style="float:left" />
     </picker>
