get upper and lower limit from imcontrast

if true
  function adjust_contrast_Callback(hObject, eventdata, handles)
axes(handles.axes1);
h = imshow(handles.I);
dbh = imcontrast(handles.figure1);
set(dbh, 'CloseRequestFcn', @(s,e)getValues(s))
waitfor(dbh);
I = get(h,'CData');
handles.I = I;
imshow(handles.I);
end
%the callback function for when the user closes the imcontrast window
function getValues(dbh)
  window_min = str2double(get(findobj(dbh, 'tag', 'window min edit'), 'String'));
  window_max = str2double(get(findobj(dbh, 'tag', 'window max edit'), 'String'));
  contrast = [window_min window_max];
  handles.contrast = contrast;
I'm able to get the values but I can't close the imcontrast window anymore, I tried close() didn't work... anyreason why would this happen?
thank you!
