Always assume that there is another person on your computer watching what you are doing if it is connected to the Internet.
Plan your Bitcoin storage accordingly.

If you are changing your passphrase for your bitcoin-qt wallet then you will still need to move all your balance to a new address (assuming your concern is someone being able to crack your old passphrase).
I am pretty sure that the unused private keys in your key pool are discarded at the point of changing your passphrase so after changing the passphrase (and making sure you keep a backup of your old wallet) send the funds to a new address (and of course backup again).
And as others have already pointed out - bitcoin-qt can't do cold storage unless you are running it from a computer that isn't connected to the internet.
cold wallet is never sync with the blockchain?

As long as Bitcoin QT connects to the Internet at any point, makes it a hot wallet.
Doesn't matter if you changed the passphrase or password you used to encrypt it.
Cold wallet = never touches the internet

If you have your coins and private keys on an online wallet like say Blockchain.info, Coinbase, or Circle, pretty sure it's still a hot wallet.
Only true Cold Wallet, is an always offline PC or storage hard drive, or the safest bet, a paper wallet.

You question is completely flawed as 100 online wallets could do things in 100 different ways.
You might want to think about your question a bit more if you want a serious answer.

My question is simple. If i have an online wallet and then i change the password of this and not spent any bitcoin from that time do i have again a cold wallet?
