function stopCount() {
    clearInterval(timer);
}

function resetCount() {
    document.getElementById('counter').innerHtml = 0;
}

And use jQuery to attach event listeners to some html element, or if you are never going to get complicated enough to need it, just stick them in the onclick properties as recommended by SimonMayer.
