Why is the JQuery hotkeys triggering more than once for shortcut

Question

I have the following code:

each shortcut is for different functionality, but when I use ctrl+r it displays the alert 4 times. Am I doing anything wrong? the code below looks fine for me...

I'm using chrome, but I don't think it matters

$(document).bind('keydown', 'ctrl+r', function (event) {
    alert("should be only once");
    event.preventDefault();
    return false;
});

$(document).bind('keydown', 'ctrl+1', function () {
    //other code
    return false;
});

$(document).bind('keydown', 'ctrl+2', function () {
    //other code
    return false;
});

$(document).bind('keydown', 'ctrl+3', function () {
    //other code
    return false;
});

Edit: I am using Hotkeys JQuery plugin

Make sure the JS isn't being called multiple times. You can unbind(...) it inside the callback function to see if that is what's happening.
