How do I change the value of a property in JavaScript?

var csequence = {
    light1: 0,
    light2: 0,
    light3: 0,
    light4: 0
};
var usequence = {
    light1: 0,
    light2: 0,
    light3: 0,
    light4: 0
};
var lightUp = function () {
    var answer = pickDiv()
    if (answer === 1) {
        $("#b1c").addClass("lightUp");
        window.setTimeout(function () {
            $("#b1c").removeClass("lightUp");
        }, 500);
        csequence.light1 = csequence.light1 + 1;
    } else if (answer === 2) {
        $("#b2c").addClass("lightUp");
        window.setTimeout(function () {
            $("#b2c").removeClass("lightUp");
        }, 500);
        csequence.light2 = csequence.light2 + 1;
    } else if (answer === 3) {
        $("#b3c").addClass("lightUp");
        window.setTimeout(function () {
            $("#b3c").removeClass("lightUp");
        }, 500);
        csequence.light3 = csequence.light3 + 1;
    } else {
        $("#b4c").addClass("lightUp");
        window.setTimeout(function () {
            $("#b4c").removeClass("lightUp");
        }, 500);
        csequence.light4 = csequence.light4 + 1;
    };
};

These are two sections of code from a web game I am making. Everything works perfectly except for the fact that the property values are not updated when I run the lightUp function. Why isn't this working?
