is it possible to store server returned json data in jqgrid to display columnnames models data dynamically for every request ? $("#grid").jqGrid({

        type: "GET",
        url: "",
           var columnNames = $("#grid")[0].p.colNames,
        var columnModel = $("#grid")[0].p.colNames,
        var columnData = $("#grid")[0].p.colNames,
        datatype: 'jsonstring',
         datastr: columnData,
        colModel: columnModel,
        jsonReader: {
            root: 'innerWrapper.rows',
            page: "result.gridData.outerWrapper.page",
            total: "result.gridData.outerWrapper.total",
            records: "result.gridData.outerWrapper.total",
            repeatitems: false,

        },
        gridview: true,
        pager: "pager",
        height: "auto",
        rowNum: 10,
        width:"auto",
        height:"auto",
        rowList: [10, 20, 30,40],
        viewrecords: true,
        caption:"Graph Data",
        rownumbers: true,

    });
