So again, there is no known use case where it would be necessary to add parameters at this particular point. Nor are these the only way to trigger sort or filtering. You should look at listGrid.fetchOperation and DataSource.transformRequest instead, although again it seems like you have some kind of confusion that's causing you to think you need to do things you don't.
