use ginput and pushbutton

hi, i wand to store multi click on image and save them after push done button. i store [x , y] coordinate of click in array but when click push button nothing happening . i get the click in while loop :

function pushbutton_callback(src,event , points ,names) // function callback
 display(points);

while 1
      [xi, yi] = ginput(1); % get coordinate %
      %do somthing and save to array click points%
      imshow(imageCopy);% image to show for click%
      b = uicontrol('Style','pushbutton','Callback',{@pushbutton_callback ,points ,names}); %button%
end

when i click on the button the [x,y] is the past click and not change and nothing happen and run loop again, how to stop the while loop and call pushbutton_callback function . tanx
