InlineEditing not working in custom elements?

When programming custom elements for Bricks, some control types, for example editor, have the option inlineEditing. According to the documentation, this option allows you to edit text directly in the preview. I have tried it with all text control types and with none of them the option inlineEditing had any effect. Am I right in assuming that with this option it should actually be possible to edit the text directly in builder mode and not only in the element settings panel? I would be very happy to receive a few tips,
