How to refresh DataGrid displayed store data?

[Jenya]

After I make some manipulations I extract needed model from the store of the DataGrid and change its data. I want the DataGrid to be updated.

Does anyone know how to do that?

You can simple call
grid.getStore().update(mymodel);

Works, but just for the info for other users:

Your model class might need to override equals method (comparing by id for instance) if as mymodel you pass another instance.

Yes sure, the models have to be equal somehow.
