The problem: Internet Explorer 8 and below don’t support the ‘bind’ method (not to be confused with jQuery’s .bind()).

To fix, simply add the .bind method to the Function prototype.  Instructions to do that can be found here.

if (!Function.prototype.bind) {
 Function.prototype.bind = function (oThis) {
 if (typeof this !== "function") {
 // closest thing possible to the ECMAScript 5 internal IsCallable function
 throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable");
 }

var aArgs = Array.prototype.slice.call(arguments, 1),
 fToBind = this,
 fNOP = function () {},
 fBound = function () {
 return fToBind.apply(this instanceof fNOP
 ? this
 : oThis || window,
 aArgs.concat(Array.prototype.slice.call(arguments)));
 };

fNOP.prototype = this.prototype;
 fBound.prototype = new fNOP();

return fBound;
 };
}
