Backbone and Datatable not syncing

I have a backbone collection model which is speaking to my backend and waht I want to do is connect it to a webix datatable. The problem is that nothing happens. If I load the data directly it seems to work but with backbone nothing happens.

Not sure how to embed code here, so here is a gist of the code:

a) It will be better to use

@config.backbone_collection ( _settings will work for webix_debug.js only )

b) onAfterRender may be called more than once, so the sync command will be executed multiple times as well ( must not be critical if you are using Webix 2.x )

c) Please be sure that you are including webix.js on the page AFTER backbone.js. Webix will enable additional handlers only if backbone was detected on the page
If you are using some complex js loading logic - you can set window.Backbone to some not empty value before loading webix.js, it will be enough to enable Backbone integration.
