Description

If you manually set the value of a text field, the 'change' event is not fired. Testcase:

var txt = Ti.UI.createTextField({
	enabled: true,
	hintText: 'change me'
});

txt.addEventListener('change', function(e) {
	Ti.API.info('text changed');
});

var btn = Ti.UI.createButton({
	bottom: 0,
	title: 'Change Text'
});

btn.addEventListener('click', function(e) {
	txt.value = 'Yay, text changed!';
});
$.win.add(btn);
$.win.add(txt);

When I change the text by focusing the textfield and typing the event is correctly fired, but if I click the button the event is never fired. Thanks.

I ran your code and it was working as expected. I clicked the button "Change Text" and the event got fired. Test case

   var win=Ti.UI.createWindow({
       backgroundColor:'white'
   });
    
   var txt = Ti.UI.createTextField({
       enabled: true,
       hintText: 'change me'
   });
    
   txt.addEventListener('change', function(e) {
       Ti.API.info('text changed');
   });
    
   var btn = Ti.UI.createButton({
       bottom: 0,
       title: 'Change Text'
   });
    
   btn.addEventListener('click', function(e) {
       txt.value = 'Yay, text changed!';
   });
   win.add(btn);
   win.add(txt);
   win.open();

Did you run it on iOS 7.1, 3.2.2GA? I just re-tested it on the iOS simulator and it didnt work as expected, event is NOT fired for me. The only different thing that I have from you is that mine is an alloy project, so my window is defined in a .xml file. Could this be an alloy problem? Thanks.

I can reproduce this issue but it appears to be an iOS behavior as we can reproduce this behavior with a native iOS application. Please see ticket TIMOB-16318 for more information. Resolving this ticket as a duplicate of TIMOB-16318.
