何处将选择更改绑定到.kv

Question

在以下kv部分：

TabbedPanelItem:
        id: tab2
        text: 'VIEW'
        on_press: root.viewInit()
        ListView:
            id: view_list
            adapter: 
                ListAdapter(
                data= root.valid_views,
                selection_mode='multiple',
                allow_empty_selection=True,
                cls=ListItemButton)

我在哪里插入on_selection_change: root.somefunc()来绑定并捕获ListAdapter中的选择更改事件？

                allow_empty_selection=True,
