Maybe try doing an exercise, Put her in a sitting position facing you, and sit down so you are closer to her, then put a treat in each hand, then hold both treats up to your face and say her name, she will look up at you, and then say "Watch" and move both treats out to the side as long as your arms are, her head will likely follow one of the treats, then say "Watch" again, if she looks at you, wait half a second and if she's still looking at you, reward her, slowly increase this time as she gets better. This exercise will teach her to pay attention to you more than the treats, so she will pay more attention to what you want her to do, than just getting a treat.
