line45 should be:

    list_item
            .downcast_ref::<ListItem>()
            .expect("Needs to be ListItem")
            .property_expression("item")
            .chain_property::<ItemObject>("number")
            .bind(&label, "label", Widget::NONE);

you should downcast to ListItem first.
