<checkbox-group class="checkbox-group1" bindchange="checkboxChange">

<checkbox class="checkbox1" data-ts="hello" value="timer1" checked="{{dataLlist.timer1_status}}" />定时1

<checkbox value="timer2" checked="{{dataLlist.timer2_status}}" />定时2

<checkbox value="timer3" checked="{{dataLlist.timer3_status}}" />定时3

</checkbox-group>

在点击“定时3”这个文字时，“定时1” checkbox选中状态会变化，这是BUG？还是我用错？
