I have a grid which is loaded and I am trying to click on the check box in the first row. I was wondering if it is possible to chain together a composite query and if so how do you do that?

Code:
it('should check the box in the first row', function() {
        ST.component('[stateId=\"basket-results\"] => [data-recordindex=\"0\"] => span.x-grid-checkcolumn') // I know this is wrong, but how do you chain a composite query?
        .click();
    });
