creating uicontrol in gui without using guide

I made a gui using guide. But in my .m gui I need to create a uicontrol but not using guide. The problem I have is that when I create a uicontrol('Style','Edit','Position',[Posx,Posy,w,l]) it plots the uicontrol well, but when I change the position the previous uicontrol is still seen, therefore I have two uicontrols, it seems it does not update the uicontrol and just creates new ones everytime I press a callback button to update the position. If I use the uicontrol in guide it does not show this problem, but I dont want to create it from guide, I will like the user to create a uicontrol if he needs too.

Where in your code are you calling UICONTROL to create the editbox?

You can move the UICONTROL:

Pos = [0.0, 0.0, 0.1, 0.04];
EditH = uicontrol('Style', 'edit', ...
     'Units', 'normalized', ...
     'Position', Pos);

for i = 1:100
  Pos(1:2) = [rand * 0.9, rand * 0.96];
  set(EditH, 'Position', Pos);
  drawnow;
  pause(0.5);
end

If your program creates new UICONTROLs, when a callback runs, it (sorry) creates new UICONTROLs instead of moving the existing one. Please inspect (or post here) the code used for the intentional moving.
