I know this question is a year old but let me post this for the sake of feature visitor of the page.

Check this out:

ko.bindingHandlers.numericnumbers = {
init: function (element) {
    $(element).on('keypress', function (number) {
        number = (number) ? number : window.event;
        var charcode = (number.which) ? number.which : number.keyCode;
        if (charcode > 31 && (charcode < 48 || charcode > 75))
            number.preventDefault();
    });
}};
