You see Hinata didn't care about her sister being kidnapped. That's surprising cause she was kidnapped.

I think it was Hinata's plan to get Naruto brainwashed to loving her.

She cared. First, she was included in the rescue mission by her own request (Kakashi said so) and then she was blaming herself that she must be a bad sister because Hanabi got kidnapped and she is knitting a scarf instead of looking for her (right before Naruto confesses).

And manga showed it pretty clear that Naruto can't be brainwashed, it was other way around :D Not too mention that Uzumaki fall for her because of Toneri's genjutsu :)
