How to refresh jqgrid using the response data returned from the edit - asp.net-mvc-4

Question

I am using the inlineNav edit options for Adding and Editing rows. The data is being updated to the database correctly, but I can't find a way to refresh the grid after a successful save without posting back to the server.
All of the Questions & Answers that I find recommend doing
$.('grid').trigger('reloadGrid');
But that seems unnecessary if the response from the server already contains the required data. It is primarily an issue when adding a new record and the ID value is displayed as jqg1.
I am using ASP.NET MVC4, with jqGrid 4.4.4.
Here is my view
$(document).ready(function () {
var emptyMsgDiv = $('<div>No school codes to display.</div>');
var grid = $('#tblSchools');
grid.jqGrid({
datatype: 'json',
viewrecords: true,
url: '#Url.Action("SchoolsGridData")',
editurl: '#Url.Action("EditSchoolsGridData")',
colNames: ['School ID', 'Name', 'SACE Number', 'School Code', 'LEA Code', 'DFEE Code', 'Active'],
colModel: [
{ name: 'SchoolId', index: 'SchoolId', width: 80, key: true },
{ name: 'Name', index: 'Name', width: 190, editable: true },
{ name: 'SaceSchoolNumber', index: 'SaceSchoolNumber', width: 105, editable: true, sortable: false },
{ name: 'Code', index: 'Code', width: 105, editable: true, sortable: false },
{ name: 'LeaCode', index: 'LeaCode', width: 80, editable: true, sortable: false },
{ name: 'DfeeCode', index: 'DfeeCode', width: 80, editable: true, sortable: false },
{ name: 'Active', index: 'Active', width: 80, editable: true, sortable: false }
],
shrinkToFit: true,
height: "100%",
caption: 'School list',
rowNum: 10,
rowList: [10, 15, 20],
emptyrecords: 'No school codes to display.',
pager: '#schoolsPager',
loadComplete: function () {
var count = grid.getGridParam();
var ts = grid[0];
if (ts.p.reccount === 0) {
grid.hide();
emptyMsgDiv.show();
} else {
grid.show();
emptyMsgDiv.hide();
}
}
}).trigger('reloadGrid', [{ page: 1 }]);
emptyMsgDiv.insertAfter(grid.parent());
grid.jqGrid('navGrid', "#schoolsPager", { edit: false, add: false, del: true });
grid.jqGrid('inlineNav', '#schoolsPager', {
addParams: {
position: "last",
addRowParams: {
"keys": true,
"aftersavefunc": function (rowid, response) {
alert('row: ' + rowid + ', response: ' + $.param(response));
}
}
},
editParams: {
"aftersavefunc": function (rowid, response) {
alert('row: '+rowid+', response: '+response);
}
}
});
});
</script>
<h3>Maintain Schools</h3>
<table id="tblSchools"></table>
<div id="schoolsPager" class="gridPager"></div>
and my Controller
public JsonResult EditSchoolsGridData(string oper, string SchoolId, string Name, string SaceSchoolNumber, string Code, string LeaCode, string DfeeCode, string Active)
{
[Update Logic]
return SchoolsGridData(string.Empty, "asc", 1, 10);
}
[HttpGet]
public JsonResult SchoolsGridData(string sidx, string sord, int? page, int? rows)
{
[Get data logic]
}
I can see the response json being displayed in the aftersavefunc, but can't find a way to bind it to the grid.
Is what I'm trying to do even possible?

You can use the addRowData method which will set the data to grid with our reloading the grid
jQuery("#tblSchools").jqGrid('addRowData', response.SchoolId, response, "first");
See the jqgrid methods wiki for more details
