Ok, I have strong reasons on why Tia was working with Beckette and using both sides.
My theory, with Jack's past, is that Tia betrayed him in the past and possibly tried to kill him. Maybe similar to what Liz this but alot more difference in a sense that Jack may felt something... I'm not doing shippy wars, just in case you guys think so.
JACK
Why should I sail with any of you? Four of you have tried to kill me in the past.
(he gets to Elizabeth)
One of you succeeded.
Will is startled. Jack notices.
JACK (cont'd)
She hasn't told you? Then you'll have lots to talk about while you're here.
(to Tia Dalma)
As for you --
TIA DALMA
Oh, don't tell me you didn't enjoy it at the time.
JACK
That's fair. All right, you're in.
Maybe Im way off, but I think Tia tricked Jack and handed him to Beckette. She is a voodoo chick. She probably knew in doing so, Beckette would burn the Pearl and that would cause Jack to call Davy.
