Can't filter with static data

[Alonzzzo2]

When I try to work with static data and not with the controller, after I enter a value to one of the int fields and press enter, I can see the this.data is undefined...
I took a look at the demos - static data, and didn't understand what I'm doing wrong...
Here's my js code which runs on page load:

function jsgridStart(taskID)
{
    $.getJSON("/Jobs/JobsData/" + taskID, function (data) {
        jsGridData = data;
        $("#jsgrid").jsGrid({
            height: "610px",
            width: "100%",

            filtering: true,
            sorting: true,
            paging: true,

            pageSize: 500,
            pageButtonCount: 5,
            autoload: false,
            data: jsGridData, // an array of data
            fields: [
                { name: "DeviceID", title: "Device ID", type: "text", width: 150 },
                { name: "RunResult", title: "Run Result", type: "number", width: 50 },
                { name: "JobResult", title: "Job Result", type: "number", width: 200 },
                { name: "JobResultValue", title: "Job Result Value", type: "number" },
                { name: "ExtendedResult", title: "Extended Result", type: "text" },
                { name: "Comments", title: "Comments", type: "text" },
                { name: "TimeOfRun", title: "Time Of Run", type: "text" }
            ]
        });
    });       
}

Hope this is the right way to ask for this kind of help. if not, can you please tell me how?
Thanks you very much!

I've reproduced the issue. Thank you for the report.
Anyway, filtering is completely developer responsibility (read about that in the ticket #32). That's why your filtering won't work without controller anyway.
