Google Spreadsheets中的共享用户无法调用doPost功能

Question

现在，我正在Google电子表格中使用Google Apps脚本创建一个邮件发送应用程序。 此应用程序执行以下操作。

1. 在电子表格打开时添加一个菜单来调用此应用程序。
2. 显示用于在单击菜单时输入邮件主题的UI。
3. 在电子表格opend用户按下提交按钮时，将电子邮件发送到电子表格中包含的每个地址。​​

问题

我使用时应用程序正常工作。 但是其他可以编辑电子表格的用户无法发送电子邮件（显示ui没问题）。

从dubug日志中，我发现没有调用 doPost 函数。

请告诉我这是什么问题。

程序

/*

 * create custome menu in active spreadsheet

function onOpen(e) {
  Logger.log("onOpen called");

  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var menuEntries = [
    {name: "MailSendApp", functionName: "displayAppUi"}    
  ];
  sheet.addMenu("CustomAppMenu", menuEntries);
}

/*

function displayAppUi() {
  Logger.log("displayAppUi called");

  var sheet = SpreadsheetApp.getActiveSpreadsheet();

  var app = UiApp.createApplication();

  sheet.show(app);

  return emails;

在openByID触发器中使用.getActiveSpreadsheet().getSheetByName(sheetName)代替doPost。

var ss = SpreadsheetApp.openById(_spreadsheetId);
var sheet = ss.getSheetByName(_sheetName);
