Trigger the digest cycle in callback events

[chengtie]

(I have asked the same question in handsontable, but nobody answered so far)

I want to create a corresponding textarea besides a handstontable, such that modifying the table has impact to the text and vice-versa.

Here is the JSBin.

One thing I realise is that, adding rows will not fire the watcher of dataJSON. So I use $scope.$digest() in the callback onAfterCreateRow to reflect the change of adding rows. But it raises an error Uncaught TypeError: Cannot set property 'forceFullRender' of null:

Does anyone know how to solve this? I think it is a serious problem, if 1) adding/removing rows/columns does not fire the watcher; 2) and we cannot well trigger digest cycle in their callback events.
