This code looks like it should work. What is your question? What isn't this code doing that you want it to do?

It is a bit strange to store your image with getappdata on the graphics root, instead of with guidata. You will also notice that you aren't actually saving the result anywhere, so the function you've written only rotates the original image.
If you want to rotate the image in every callback, you need to store your image back somewhere, so in your case something like this should work:
a=getappdata(0,'a');
aclock=a;
aclock=imrotate(aclock,270);
axes(handles.axes1);
imshow(aclock);
setappdata(0,'a',aclock)

Try This
global a
a=imrotate(a,270);
axes(handles.axes1);
imshow(a);
