Simple Chosen.js binding handler for knockoutjs

chosenhandler.js

//knockout.js can be found at http://www.knockoutjs.com
//chosen.js can be found at http://harvesthq.github.com/chosen/
//jquery.js can be found at http://jquery.com

//Usage is data-bind="chosen: true"
//Want to clean this up to eventually work as
//data-bind="chosen: { options: SelectOptions, value: selectValue}"

ko.bindingHandlers.chosen = {

    init: function(element, valueAccessor, allBindingsAccessor, viewModel) {
        $(element).chosen();
     },

     update: function(element, valueAccessor, allBindingsAccessor, viewModel) {
         $(element).trigger("liszt:updated");
    }

};

this binding is not working for knockout js v3.0

line 16: should be $(element).trigger("chosen:updated)
