autoForm not working in Meteor 1.11

I am new in meteor and I have learned with meteor 1.4. However, when I updated to Meteor 1.11, My code is not working anymore. I follow the same logic with some differences in code according to meteor 1.11.

This is the code I have in Js

import { Meteor } from 'meteor/meteor';
import SimpleSchema from 'simpl-schema';
import { Mongo } from 'meteor/mongo';
Books = new Mongo.Collection("books");
    Books.attachSchema(new SimpleSchema({
      title: {
        type: String,
        label: "Title",
        max: 200
      author: {
        type: String,
        label: "Author"
      copies: {
        type: Number,
        label: "Number of copies",
        min: 0
      lastCheckedOut: {
        type: Date,
        label: "Last date this book was checked out",
        optional: true
      summary: {
        type: String,
        label: "Brief summary",
        optional: true,
        max: 1000
    }, { tracker: Tracker }));

and this in HTML

<template name="insertBookForm">
  {{> quickForm collection="Books" id="insertBookForm" type="insert"}}

I do not have any error in the Windows Powershell
However, in the Browser, I have this error two errors

I think the first error shows you what’s wrong. Books collection is not global or in the window scope. Try to either provide a helper to resolve Books in the template, or declare Books as global.

Thank you, I have needed just a helper to resolve Books. That does not even pass my mind!. Thank you again.
