From Configurator 4 to HTML5

In a Configurator 4 created panel for Photoshop and I have a button for  the menu item Curves.

Here is the script that I got from script editor in Configurator. When I run this script from ExtendScript, it works perfectly.

ErrStrs = {}; ErrStrs.USER_CANCELLED=localize("$$$/ScriptingSupport/Error/UserCancelled=User cancelled the operation");

try {var idCrvs = charIDToTypeID( 'Crvs' ); executeAction( idCrvs, undefined, DialogModes.ALL );

    } catch(e){if (e.toString().indexOf(ErrStrs.USER_CANCELLED)!=-1) {;

            } else{alert(localize("$$$/ScriptingSupport/Error/CommandNotAvailable=The command is currently not available"));}}

How would I transfer (translate) the above script to the main.js file in the "Hello Word" sample extension?

Main.js

(function () {

    'use strict';

    var csInterface = new CSInterface();

    // Reloads extension panel

    function reloadPanel() {

        location.reload();

    }

    function init() {

        themeManager.init();

        $("#btn_reload").click(reloadPanel);

        $("#btn_test").click(function () {

            csInterface.evalScript('sayHello()');

        });

         $("#btn_curves").click(function () {

        });

    }

    init();

}());

Thanks so much for your help. Sam
