php - Webix Data Loading from Laravel Link -

trying load data webix data table using following code. looks browser getting json data back, webix isn't doing data. no datatable shows up, can still see full json under network -> response tab in firefox inspector. valid way of loading data webix?

<script type="text/javascript" charset="utf-8">                     dtable = new webix.ui({                         container:"box",                         view:"datatable",                         select:"row",                         scroll:"xy",                         leftsplit:3,                          url: "{{ url('/getcontacts') }}",                         datatype: "json"                     });                 </script> 

specifically, question around whether url work route 'getcontacts' returns json object.

after troubleshooting webix, determined yes. using "{{ }}"does work webix, case, grid hidden css fault collapsing rows of grid. once fixed, datatable showed data without flaw.
