多选picker修改range产生的问题？
多选picker，在bindcolumnchange中修改range后，选中的值会弹回去 startDateYearColumnChange:function({detail}){
console.log("detail", detail, this.data.startDateRange[0][detail.value]);
console.log("startDateRange", this.data.startDateRange);
if(detail.column == 0 && detail.value == 2){
this.setData({
'startDateRange[1]':[6, 5, 4, 3, 2, 1]
})
} else {
this.setData({
'startDateRange[1]':[11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
})
}
}
<picker
class="picker"
mode="multiSelector"
range="{{ startDateRange }}"
bindchange="changeStartDate"
bindcolumnchange="startDateYearColumnChange"
bindcancel="startDateSeleteCancel"

[图片] 据我分析是因为改变了range绑定值的地址改变了，求问怎么解决这个问题
