Laravel Integration with Webix Datatable Editing

I have a site that's running Laravel 5 and I'd like to create a Webix datatable within it. My understanding of Webix datatables is that these tables can be set to load data from Laravel database by using a controller, but I do not see any information on how datatable information is read and saved when the datatable is set to editable.

When the datatable is editable, do I still need to create a controller for read and write to the database? And if so, how do I know what data was changed/needs to be updated in the database?
