RibbonDropDownItem for click listening

Question

I am developing a powerpoint addin and using the ribbon constructor for this. I have a gallery element containing RibbonDropDownItems . I can’t find a way to add clicks to listen there because the RibbonDropDownItem Interface does not have a 'Click' event, for example RibbonButton Interface .

So, is there a way to catch the click event from the RibbonDropDownItem object?
