how to sync data from ydn-db web app to backend server?

[asicfr]

With ydn-dn, i want to automatically synchronise data from my web app with my REST back end.
I read the documentation and searched in examples but i cannot make it work.
https://yathit.github.io/ydn-db/synchronization.html
http://dev.yathit.com/api/ydn/db/schema.html#sync

I tried to define a schema with sync configuration like that :

var schema = {
stores: [ {
name: 'contact',
keyPath: 'id',
Sync: {
format: 'rest',
transport: service,
Options: {
baseUri: '/'
}
}
}
]
};
and created a function for transport :

var service = function(args) {
console.log("contact synch");
};
but my service function is never called.
I certainly misunderstood how YDN-db work, but i didn't found any example.

To complete, here is a jsfiddle : http://jsfiddle.net/asicfr/y7sL7b3j/

There is an example http://yathit.github.io/ydndb-demo/entity-sync/app.html

Old example http://yathit.github.io/sprintly-service/playground.html from https://github.com/yathit/sprintly-service
