I think the way to do this is by defining a boolean propertie in your viewmodel of the entity. For example
self.hasChanges = data.isChanged;
When you done this, you can simply bind this property to the enable attribute of the save button in your form
<input type="submit" data-bind="enable: hasChanges()" value="save" />
Hope this will help.
