MATLAB: Dynamically alter datatip behavior

datatipgui

I have a GUI containing an image axis and some radio buttons. I want the behavior/appearance of new figure datatips introduced into the image window to be determined based on the state of the radio buttons.
When a different radio button is selected, I update the datacursormode object's UpdateFcn. However, I find that it doesn't take effect on how new datatips look if there are prior data tips already present in the figure. After I delete the prior datatips manually, the new UpdateFcn does kick in and things work fine. Why is this necessary?
Also, if it's absolutely necessary to delete all prior data tips to make this work, how do I do so programmatically?
