Using pouchDB with crypto-pouch in ionic

After testing pouchDB for my Ionic project, I tried to encrypt my data with crypto-pouch. I used the following code:

For init my database:

 function initDB() {
   _db = new PouchDB('myDatabase', {adapter: 'websql'});
   if (!_db.adapter) {
     _db = new PouchDB('myDatabase');
   return _db.crypto(password)
       return _db;

My function to map my documents:

function mapAllTypeOne(doc) {
  if (doc.type === 'type_one') {

To get all documents of type_one:

function getAllData {
   if (!_data) {
     return $q.when(_db.query(mapAllTypeOne, { include_docs: true}))
       .then(function(docs) {
         _data = {
           return row.doc;
         _db.changes({ live: true, since: 'now', include_docs: true})
           .on('change', onDatabaseChange);
         return _data;
   } else {
     return $q.when(_data);

If I insert data of type_one, I can see it in my database and it is encrypted in the database. But I couldn’t see it in my list. After a reload (in the browser) or after closing and restarting the app (in android or iOS) the new data can be seen.

Whitout crypto-pouch the code is working well. Can anyone help me? Thanks in advance!
