Parent session is created is View.
Then I create editor of the row in chidren session. Then I start Batch operation
var session = this.getView().getSession();
var batch = session.getSaveBatch();

batch.startPromise().then(function () {
var s = session;
s.save(); // How to update parent session???
me.getView().close();
});
