var btnnext = Titanium.UI.createButton({title:'++ '});
btnnext.width=25;
btnnext.height=25;
btnnext.left=100;

btnnext.addEventListener('click', function(e)
{
    Ti.API.info("testing");
});

winContainer3.add(btnnext);
winContainer2.add(winContainer3);
win2.add(winContainer2);

win2.open();

• I think the events fires.
  Try to use Titanium. instead of Ti. inside the function
  Let me know

• Although your not using a ButtonBar here I found that any event on a button in a ButtonBar would not fire at all if the ButtonBar's width was 'auto' setting it to 100% made the buttons suddenly work! There was no discernible visual difference, just another of Titanium's API inconsistencies that keep popping up.

• I have some issues with my eventListener on a TextField. In my case only focus works. So try:

          btnprev.addEventListener('focus', function(){
              Ti.API.info('Perhaps focus will work?');
          });
  

• don't ask me why this works, but it did for me, and it might for you. i had a function

  function create_window(){
      var button = createButton(....);
      button.addEventListener(...)
      var window = createWindow(....);
      window.add(button);
  }
  

  the click wasn't firing. but when i did this:

  var button = createButton(...);
  button.addEventListener(...);
  function create_window(){
      var window = createWindow(....);
      window.add(button);
  }
  

  i'm sure it's got something to do with the contexts and scopes which i have yet to understand completely in titanium, but it works the first way in one of my scripts but only the second way in another script.

  try it on yours - good luck!
