Change keyboard focus in MATLAB GUI

I am trying to allow the user to press return or space to enter values, so whenever they press these keys, no matter where the crusor is, a certain callback must be intiated. What happens is that the GUI loses focus whenever I press on the editable fields and start writing values, but if I pressed on the button manualy the enter and space keys regain focus.
the code block where I define these keyboard keys is
function keyPressCallback(source,eventdata)
keyPressed = eventdata.Key;
if strcmpi(keyPressed,'space') | strcmpi(keypressed, 'return')
uicontrol(app.FillTableButton);
snapshot_callback(app.FillTableButton,[]);
end
end
Please anyone has an idea how to solve this issue?
Thank you

Since you mentioned you are new to MATLAB's GUI, you can refer the following documentation to help you gain more clarity in adding calbacks in Appdesigner.
