wd:TimePicker Binding 绑定不上值的问题

[yuhandbcontext]

既不能绑定值，也不能获取值，版本1.1.0.2-preview9，targetFramework="net45"
<wd:TimePicker Width="120" Name="TimePicker1" SelectedTime="{Binding Time,UpdateSourceTrigger=PropertyChanged}" />

可以设置绑定模式为 TwoWay

<wd:TimePicker Width="200" SelectedTime="{Binding Time, Mode=TwoWay}" />
