Clear 'looped' timeout closed in function - how to return id of interval that I would have ability to clear it

Question

I have two functions inside my Class. First fires timeout and looped it (works like interval) and second to clearTimeout. My problem is, that clearTimeout doesn't work. How can I fix it?

this.startMove = function() {
    setTimeout(function handler() {
        self.moveMonster(moveMonsterCallback);
        setTimeout(handler, self.speed);
    }, this.speed);
};

this.stopMove = function() {
    clearTimeout(self.startMove());
}

For example I want to run these functions on click.

Let me know if this works for you :

this.startMove = function() {
    self.timeout = setTimeout(function handler() {
        self.moveMonster(moveMonsterCallback);
        self.startMove();
    }, self.speed);
};

this.stopMove = function() {
    clearTimeout(self.timeout);
}

So basically I have reused the @Michael Horn's solution. And, I am happy to use this answer as an to his edited answer (if the question resolves).
