How to get the data from a popup menu and display the selected data in list box?

I'm having the problem that, I got one popup menu with three data and a list box. A push button which transfers the selected data from the popup menu to the list box. This is the concept. But I have the problem that, when I select one dat6a from the popup menu all the data appears instead the selected.

Is there any possibility that, the string what I selected from the popup menu can be displayed as a label for a figure?

Here is a simple example. More basic GUI examples can be found here.

function [] = GUI_pop_to_list()

S.fh = figure('units','pixels',...
              'position',[450 450 400 150],...
              'menubar','none',...
              'resize','off',...
              'numbertitle','off',...
              'name','GUI_pop_to_list');
S.pp = uicontrol('style','pop',...
                 'units','pix',...
                 'position',[10 60 190 40],...
                 'string',{'Data 1';'Data 2';'Data3'},...                 
                 'fontweight','bold',...
                 'horizontalalign','center',...
                 'fontsize',11);
S.ls = uicontrol('style','list',...
                 'units','pix',...
                 'position',[210 70 190 60],...
                 'backgroundcolor','w',...
                 'HorizontalAlign','left');
S.pb = uicontrol('style','push',...
                 'units','pix',...
                 'position',[10 10 380 40],...
                 'HorizontalAlign','left',...
                 'string','Transfer',...
                 'fontsize',14,'fontweight','bold',...
                 'callback',{@pb_call,S});
uicontrol(S.pp)   % Give the editbox control. 

function [] = pb_call(varargin)
% Callback for edit.
S = varargin{3};
E = get(S.pp,{'string','value'});
STR = get(S.ls,'string');
set(S.ls,'string',[STR;E{1}(E{2})])
