SquirrelFish seems to miss "bind()", how to bind a JS callback to "this" without it?

Question

anybody knows who to bind a JS callback to "this" without "bind()"?

according to Samsung specs:

2013 is on V8 : works fine (see linked shot, too large to add)

2012 is on SquirrelFish : gets exception: "bind()" is not available as a function (see linked shot, too large to add)

the offending code is this:

		var extJsCallBacks = [
          function(){this._setupSystemInfo();}.bind(this), 
          function(){this._setupConfigInfo();}.bind(this),
          function(){this._setupRepository();}.bind(this), 
          function(){this._setupContents();}.bind(this)
          ];

any hints?

Polyfill found on MDN

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,
                 aArgs.concat(Array.prototype.slice.call(arguments)));
        };

    if (this.prototype) {
      // Function.prototype doesn't have a prototype property
      fNOP.prototype = this.prototype; 
    }
    fBound.prototype = new fNOP();

    return fBound;
  };
}
