> The `ExpressionEditorChanged` it's being fired many times.
> Check the scenario:
> When the `DMNGridLayer.select(GridWidget)` method is called, it calls `BaseGridWidget.select()`. This will trigger the `ExpressionEditorChanged` X times, where X is the number of grids on the layer. This is not optimal.
> Check the same problem in the `deselect` method.
