Bind with coffeescript -

How can I call the original bind function of the function object with coffeescript? This is the example I am trying to get:

  window.addEventListener ("load", function (e) {this._filter (true);} .bind (this) ;) Add some brackets around the function so that you can  .bind    
 
 True thing:  
  window.addEventListener ('load', ((e) -> gt; this._filters (true)) stop (this))   
 This will normally use the basic code instead of the  var _this = this  trailer, which is the value of the coffee script's  = & gt;  uses
