Trying to make this asynchronous

asyncAttempt.js

// create array to hold the values that the memory tiles will hold
var memory_values = [];
// create array for the locations of the tiles themselves
var memory_tile_ids = [];
// initialize array for the tiles flipped
var tiles_flipped = 0;

function onLinkedInLoad() {
  IN.Event.on(IN, "auth", function() {
    onLinkedInLogin();
  });
  IN.Event.on(IN, "logout", function() {
    onLinkedInLogout();
  });
}

function onLinkedInLogout() {
  // setConnections({}, {total:0});
}

function onLinkedInLogin() {
  // here, we pass the fields as individual string parameters
  IN.API.Connections("me")
    .fields("id", "firstName", "lastName", "pictureUrl", "publicProfileUrl")
    .result(function(result) {
      listConnections(result.values, arrFilter);
    })
    .error(function(err){
      alert(err);
    });
}

function listConnections(connections, callback) {
  callback(connections, shuffleArray1);
}

function arrFilter(arr, callback) {
  var filteredArr = arr
    .filter(function(element){
      return element["id"] != "private";
    });
  callback( filteredArr, arrLimit12 );
}

function shuffleArray1(arr, cb){
    var i = arr.length,
      j,
      temp;

    // i starts at the length of the array
    // then immediately decrements  
    while( --i > 0 ){
      // reshuffles the array tiles randomly
        j = Math.floor(Math.random() * ( i + 1 ));
        temp = arr[j];
        arr[j] = arr[i];
        arr[i] = temp;
    }
    cb(arr, createMemoryBoardArray);
}

function arrLimit(arr, arrLen){
  return arr
    .slice(0,arrLen);
}

function arrLimit12(arr, cb){
  var newArr = arrLimit(arr, 12);
  // cb = createMemoryBoardArray
  cb( newArr , newBoard);
}

function createMemoryBoardArray(objArr, cb) {
  var linkinBoard = [];
  objArr.forEach(function(element){
    linkinBoard.push({
      linkinType: "name",
      id: element["id"],
      name: element["firstName"] + " " + element["lastName"]
    });
    linkinBoard.push({
      linkinType: "image",
      id: element["id"],
      imageUrl: element["pictureUrl"]
    });
  });
  // cb = newBoard
  cb(linkinBoard, shuffleArray2, '');
}

// And it keeps going on like this...
