title: Call Back Function for Popup menu in Matlab
body: <p>I have generated a popup menu without using GUIDE by using following code which works well:</p>
  
  <pre><code>figure;
  row=4;
  String =sprintf('Video%d#', 1:row);
  String(end) = [];
  CString=regexp(String , '#' , 'split');
  uicontrol('style','popupmenu' , ...
      'String' , CString ,...
      'Position' , [200,400,12,24]);
  </code></pre>
  
  <p>My problem is its callback function, I can not assign any function to that to have any action when I press any of it's option.</p>
  
  <p>I will appreciate that anyone help me.</p>
