A problem with Function.prototype.bind polyfill

I met an issue with the common polyfill for Function.prototype.bind, found on the MDN, and I do not know where to fix it.

Here is the polyfill:

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');
