Simulate a ember-select2 selection in ember integration test

Has anyone been able to simulate a select2 selection of an option? So far I've tried this:

 test("Checking navigation", function () {
      expect(1);
      visit("/hub");
      click("#btnLogin");
      andThen(function () {
        click(".select2-container");
        andThen(function () {
        });
      });
    });

But I have not seen changes in the UI.
