无法通过salesforce混合应用程序(forceios）调用RESTAPI

我通过forceios创建了一个混合salesforce应用程序，可以显示所有联系人。

但现在我想显示报告，所以我使用了REST API，但方法

forcetk.Client.protype.ajax

没有被调用，xcode或浏览器中没有显示错误。

我已经和你共享了app.js文件，请帮我。。。

app.js

var forceClient；

（函数（）｛

"use strict";
/* Adding platform (ios/android) specific css */
var platformStyle = document.createElement('link');
platformStyle.setAttribute('rel', 'stylesheet');
if (/Android/.test(navigator.userAgent)) {
    platformStyle.setAttribute('href', 'css/ratchet-theme-android.css');
} else if (/iPhone/.test(navigator.userAgent)) {
    platformStyle.setAttribute('href', 'css/ratchet-theme-ios.css');
}
document.querySelector('head').appendChild(platformStyle);

    authenticateUser(showUsersList);
