jQuery Grid Plugin - jqGrid

I posted this on here http://stackoverflow.com/quest.....ading-data

Am new to JQGrid. I set up the grid following the examples given here using the Html JQGrid helper class under my view. Trirand MVC - JQGrid

from the example - it has 2 functions in the controller, first one is ActionResult PerformanceLinq() - which is just returning the view. second one is JsonResult DataRequested() - this returns the data in jqgrid model: return gridModel.OrdersGrid.DataBind(northWindModel.Orders);

So, I have all my data loaded perfectly, rendered. Done as far as the first step.

I have a textbox, and a search button (they both aren't JQGrid components). onclick event should trigger an ajax call to DataRequested() method, which I modified a bit passing a parameter. How can I refresh myGrid without rendering the page again?

function GetAccountSearchGrid() {
        debugger;
        var myKey = document.getElementById('SearchKey').value; //this is searchKey value

        $.ajax({
            url: '@Url.Action("AccountSearchGridDataRequest")',
            type: 'GET',
            data: {
                id: myKey
            },
            dataType: 'json',
            contentType: 'application/json',
            success: function (data) {                    
                jQuery('AccountSearchGrid1').jqGrid('clearGridData');
                jQuery('AccountSearchGrid1').jqGrid('setGridParam', { data: data });
                jQuery('AccountSearchGrid1').trigger('reloadGrid');
                //$('#AccountSearchGrid1').jqGrid('setGridParam', { data: data }).trigger('reloadGrid');
                //jQuery("#AccountSearchGrid1")[0].p.data = data;

            },
            error: function (data) {
                alert("error");
            }
        });
    }

Please keep in mind that AccountSearchGridDataRequest(searchKey) returns a gridmodel 
- so how can I bind the JsonResult into the grid, in Ajax success inline?
here's my c# controller code for getting the data
public JsonResult AccountSearchGridDataRequest(string id)
        {
            JobDefinitionContact jc = new JobDefinitionContact();
            if (!String.IsNullOrEmpty(id)) { jc.CompanyName = id; }

            var jobDefServiceClient = new JobDefServiceClient();            
            var acctSearchResult = from i in jobDefServiceClient.GetAccountSearch(jc, "100")
                                   select i;
            IQueryable<JobDefinitionContact> searchItems = acctSearchResult.AsQueryable<JobDefinitionContact>();
            var gridModel = new JobDefinitionAccountSearchGridModel();
            SetUpGrid(gridModel.AccountSearchGrid, id);

            return gridModel.AccountSearchGrid.DataBind(searchItems);
        }
