loading a webpage via inAppBrowser, in index.js

'
ref = cordova.InAppBrowser.open(env, '_blank','clearcache=no,location=no, clearsessioncache=no, footer=no,zoom=no' );

    new jQuery(function(){

                        new jQuery(".iscroll-wrapper").bind({
                            iscroll_onpulldown: onPullDown,
                            iscroll_onpullup: onPullUp
                        });

                                console.log( "ready!" );
