I do this in my app. All of my forms are data-driven, so when the data is initially loaded from the server I create two copies of it: formData and formDataOnFile. I then broadcast an event any time something changes, and in the event handler I use ObjectUtil.compare(formData, formDataOnFile) to determine whether or not they're identical. If they're not then I enable my save button.
