 If you want to run a callback you must use __edit-callback__ attribute with a valid function and it will run every time the model value is __changed__.
 
 Since version __1.2.0__, after issue [#13](https://github.com/codekraft-studio/angular-content-editable/issues/13) you __MUST__ specify the arguments `text, elem` if you want to use them in your callback, like in this example.
