How to create a callback for radio buttons

I have a group of radio buttons with 3 choices (app.mode1, app.mode2, and app.mode3) in app-designer. When a user clicks one of the radio buttons, I want the name of a separate button to be changed to something else. For example: mode 1: "load", mode 2: "plot", mode 3: "display". I'm able to create a call back for the group of radio buttons as below:
function modeSelectionChanged(app, event)
selectedButton = app.mode.SelectedObject;
end
end
But I have no idea as to how to write the following codes. Would someone please help me out?
Many thanks!

Assuming your button has the name app.Button, and your radio buttons are labeled 'Mode1', 'Mode2', and 'Mode3', something like this
% Selection changed function: Mode
function ModeSelectionChanged(app, event)
selectedButton = app.Mode.SelectedObject;
switch selectedButton.Text
case 'Mode1'
app.Button.Text = "Load";
case 'Mode2'
app.Button.Text = "Plot";
case 'Mode3'
app.Button.Text = "Display";
end
end

What are you expecting it to do?
When I tested it, it changes the displayed text on app.Button based on the selection of the radio buttons. Again, you must label your buttons 'Mode1', etc for it to work.
You can make it a little more generic if you use the Value property instead
% Selection changed function: Mode
function ModeSelectionChanged(app, event)
selectedButton = app.Mode.SelectedObject;
switch selectedButton.Value
case 1
app.Button.Text = "Load";
case 2
app.Button.Text = "Plot";
case 3
app.Button.Text = "Display";
end
end
