model view controller - Fill jqgrid with data from visualforce page -

I have a visual platform and I am using jqgrid to display data on this page. The URL that jqgrid indicates is a visualforce page () which outputs only JSON data. This page does not contain any header or HTML information

The problem is that when I run this page, the grid gives the column names but no data. When I run the URL it outputs JSON data. I have pasted the code below.

  jQuery ("#list"). JqGrid ({url: "https://test.visual.force.com/apex/GridResults", Datatype: "[Json], colNames: [{fieldNames}], - The call modal for the field names in the property that contain: [ {Colemodel}], - Controller property which column definition line output: 10, line total: 10, line list: [20, 40, 60], loadonas: true, mount: "gate", grid view: right, pager: ' Jquery ("#list") .jqGrid ('navGrid', 'Sort'), Sort Order: "Record ID", Sort Order: "Dis", Width: 1200, Height: 400, Caption: "Account Book"}) "#pager", {edit: true, add: true, d L: wrong}}};  

Any information on this page is not used by the Jackgren,

have you checked the visual remoting?
