JavaScript：函数未被调用

Question

我在此功能结束时调用函数calculateAndDisplayRoute(1)时遇到问题。我检查了FireFox Developer，发现所有其他代码都正确执行，除了这一行。任何人都可以看到任何问题吗？

function adjustHex(diff, total) {
    //....
    var nearest = total;

    for (var i = 0; i < eightPoints.length; i++) {
        for (var j = 0; j < eightPoints.length; j++) {
            //....
            checkThisHex(tempPoint1, tempPoint2, 2, function (current) {
                var bool = compareHex(current, nearest); // returns true if current is closer than the nearest

                if (bool == true) {
                    document.getElementById("printInfo3").innerHTML = current;
                    nearest = current;
                    fillWaypts(tempPoint1, tempPoint2);
                }
            });
        }
    }

    calculateAndDisplayRoute(1);
}
