Rebuild don't recognize changes maded on widget

Hello to everyone,

I'm a newbie with Titanium. I'm using some widgets to start my project, but when I made changes on widget.js file and rebuild I can't see the anything new on app. I'm try using "ti build -p android" and then installing the result apk using adb and using directly the play button on Titanium 3.2.2.

How can I do to tell Titanium to re read changes on widget sources when rebuild the app ?

Thanks in advance
