Grid Editor Field - Combobox instead of TextField

Hi everyone,
I'm trying to use inbuilt editor of grid to update objects
grid.setEditorEnabled(true);

it works fine. now i want to use comboBox to let user choose available items from database instead of letting him type.
I tried this but it doesnt work, i still get textField.

ComboBox cb= new ComboBox();
        List<Container> data = containerService.findAll();
        BeanItemContainer<Container> bicCb= new BeanItemContainer<>(Container.class);
        bicCb.addAll(data);
        cb.setContainerDataSource(bicCb);
        cb.setItemCaptionMode(ItemCaptionMode.PROPERTY);
        cb.setItemCaptionPropertyId("name");
grid.getColumn("from.name").setEditorField(cb);

does anyone have any idea how to change textField of editor to comboBox or something else?
