When a user edits a cell/row and presses enter, the cell is marked as dirty. However, the Save and Cancel buttons remain disabled, thus the user should focus on a different cell before being able to save changes.
The cell is closed and marked as dirty, the 'Save changes and 'Cancel changes' buttons remain disabled.
The buttons should be enabled once the cell is marked as dirty.
cellClose: function(e){
e.sender._toggleToolbarEditingItemsVisibility()
},
