Keep getting the error:

Undefined function 'ImageClickCallbackHand' for

input arguments of type

'matlab.graphics.primitive.Image'.

Error while evaluating Image ButtonDownFcn.

Trying to make a GUI that has an image which I can get the coordinates from when GUI is running. The image appear on axis when Calibration Button is pressed.

function ImageClickCallbackHand (objectHandle, eventData)
    app.axesHandle  = get(objectHandle,'Parent');
    app.coordinates = get(axesHandle,'CurrentPoint'); 
    app.coordinates = app.coordinates(1,1:2);
end
function CalibrationButtonPushed(app, event)
    myImage1 = imread('hand2.png');
    resizePos1 = get(app.UIAxes, 'Position');
    myImage1 = imresize(myImage1, [resizePos1(3) resizePos1(4)]);
    imageHandle1 = imshow(myImage1,'Parent',app.UIAxes);
    set(imageHandle1, 'ButtonDownFcn',@ImageClickCallbackHand)
end
