If your really want her to do tricks etc when YOU want, then you have to find the "magic" treat. Find what makes her to MAD over something. Starts licking her lips and is 100% fixed on you/it. Only give that treat when she does as you say, but not too often that she takes it for granted.
It took me some time to find what was Gizmos fix…sadly....it's fish, something I can't stand. But he goes nuts when he smells it, and seeing me holding a little piece he starts going in spins on the floor smacking his lips.
I give a command, and he will do it...sometimes will walk away, acting all hard to get, but it's too irresistible for him and he turns right back after a few steps..eventually he does the trick...hehe.
