You might try giving her a treat - it can even be a piece of kibble - every time she DOES come to you when you call her name. Keep some kibble in your pocket, call her like you were calling her to a party - all excited and animated...even get down to floor level, head and all...and especially when you give her the treat, say her name, all excited, giving confirmation, and 'good girl'.
On the other hand, are you sure there isn't a hearing problem with her? Does she react to sounds, like the squeak of a toy, when she can't see it?
