Listening for variable changes in JavaScript or jQuery

How can I track if this variable has changed?

var ConditionalFlag = 0;

I tried this:

var ConditionalFlag = 0;

$(ConditionalFlag).change(function () {

    alert(Changed);

});

ConditionalFlag++;

But to no avail. I have considered using a 25ms timer to check for change like this:

var ConditionalFlag = 0;

function CheckFlag() {

    if (ConditionalFlag > 0) {

        alert(Changed);

        clearInterval(check);

    }

}

var check = window.setInterval(CheckFlag(), 25);

ConditionalFlag++;

However, that seems like overkill. Is there a way to attach an event handler to this variable with jQuery or javascript?
