How do I use the buttondownfcn on UIAxes in the new 2017a Matlab? I know the functionality is there.

I'm plotting a contour and I want to access the points where the user clicks.

There is no ButtonDownFcn function for UIAxes. There is for Axes but not for UIAxes.

I don't understand why. Can someone from mathworks explain or give a workaround?
