I have a funny workaround for your problem. For paste event you may use the following code:

$("input").on("paste", function(e) {
    var that = this;
    that.style.color = "#fff";      // field background color
    setTimeout(function() {
        that.value = that.value.replace(/\D/g, "");
        that.style.color = "#000";  // normal field font color
    }, 100);
});​
