What is the template engine that is being used and can we extend it to add helpers? What I want to do is have a specific list value be

.toFixed(2)

.

I tried following the instructions and it failed to load the helper. However I loaded Handlbars into the View and registered the helper that way. Is it that more recent versions don't work the same way? This is what worked for me.

define("CAFB.EditOrder.CartDetails.View"
    , [
        "cafb_editorder_cart_details.tpl"

        , "CAFB.EditOrder.Main.SS2Model"

        , "Backbone"

        , "Handlebars"
    ]
    , function (
        cafb_editorder_cart_details_tpl

        , MainSS2Model

        , Backbone

        , Handlebars
    ) {
        "use strict";

        // @class CAFB.EditOrder.CartSummary.View @extends Backbone.View
        return Backbone.View.extend({

            template: cafb_editorder_cart_details_tpl

            , initialize: function (options) {
                Handlebars.registerHelper("currency", function (value) {
                    return parseFloat(value || "0").toFixed(2);
                });
            }
        });
    });
