Accessing multiple return values (a, b, c) from hardness function in web3js

I have a function that returns multiple values. I want to access them from Web3js.

function testReturnBet(uint index) constant returns (address player, 
                                                     uint tokensPlaced, 
                                                     uint8[4] numbers,
                                                     uint ratioIndex,
                                                     uint timestamp,
                                                     uint rollIndex,
                                                     uint winAmount) {
        bet outBet = bets[index];
        return (outBet.player,
                outBet.tokensPlaced, 
                outBet.numbers, 
                outBet.ratioIndex, 
                outBet.timestamp, 
                outBet.rollIndex, 
                outBet.winAmount);
    }

You will get an array of return values with 7 values (0-6). The third should be an array with 4 values.

In truffle style, it looks something like this:

contract.testReturnBet(index).then(function(response) {
  console.log(response); // should be an array
});
