Problem

PickerRow events are not registering as documented.

Test Code

var win = Titanium.UI.createWindow();

var picker = Titanium.UI.createPicker();

    row1=Titanium.UI.createPickerRow({title:'Row 1'});
    row2=Titanium.UI.createPickerRow({title:'Row 2'});
    row3=Titanium.UI.createPickerRow({title:'Row 3',stellarLevel:3});
    
picker.add(row1);
picker.add(row2);
picker.add(row3);
win.add(picker);

    row1.addEventListener('click',function(){
    Ti.API.info('CLICK');
    });
    
    row2.addEventListener('touchstart',function(){
    Ti.API.info('TOUCH');
    });
    
    row3.addEventListener('touchend',function(){
    Ti.API.info('TOUCH');
    });
    
    picker.addEventListener('change', function(e){
    Ti.API.info(picker.getSelectedRow(0).title);
    });

win.open();
