Scroll bar and MouseEnteredCallback

I apologize in advance for my English. Events are triggered only when you hover over a listbox, but do not work when you hover over the scroll bar. How can I fix this?

 function primer()
  simFigure = figure(123);
  set(simFigure, 'Name', 'Simulation', 'NumberTitle','off');
  set(simFigure, 'Units','norm', 'Position', [0 0 1 1]);
  set(simFigure, 'RendererMode', 'manual');
  set(simFigure, 'Renderer', 'zbuffer');
  set(simFigure, 'Color', [0.941 0.941 0.941]);
  listParWork = uicontrol('Style', 'listBox', 'Units','norm', 'Position',[0.068 0.71 0.12473 0.07978],...
      'FontSize',8, 'Tag', 'parWork', 'Parent', simFigure);
  jButton = findjobj(listParWork);
  jListbox = jButton.getViewport.getView;
  jListbox = handle(jListbox, 'CallbackProperties');
  set(jListbox,'MouseEnteredCallback', {@enterListPar,listParWork});
  set(jListbox,'MouseExitedCallback', {@exitListPar,listParWork});
 end

 function enterListPar(~,~,list)
  set(list, 'Position', [0.068 0.63 0.12473 0.15978]);
 end

 function exitListPar(~,~,list)
  set(list, 'Position', [0.068 0.71 0.12473 0.07978]);
 end
