Jquery Grid row remains in the edited form saveRow event is called and another row is clicked - jquery-plugins

Question

I have a grid that is loaded inside a jquery dialog. I have done row editing and row saving within onSelectRow event. When a row is edited and saved and then another row is clicked, previous row remains in the edited form. I am not able to save and remove the edited form.
Id of my table on which I want to load the grid is MultiCount.
And I have binded the grid inside a function bindShapesGrid(), below is the code.
I have hardcoded a XML String and used it as the data.
function bindShapesgrid() {
var xmlstring = "<root><rows><row><cell>Shortnamevalue</cell><cell>does not equal</cell><cell>and</cell><cell>sad</cell><cell></cell><cell></cell></row><row><cell></cell><cell></cell><cell></cell><cell></cell><cell></cell><cell></cell></row></rows></root>"
var lastsel2;
jQuery("#MultiCount").jqGrid({
datatype: 'xmlstring',
datastr: xmlstring,
colNames: ['ShortName', 'Operand 1', 'Value 1', 'AndOr', 'Operand 2', 'Value 2'],
colModel: [{ name: 'ShortName', index: 'ShortName', align: 'center', width: 80, editable: true, edittype: "select" },
{ name: 'Operand1', index: 'Operand1', align: 'center', width: 90, editable: true, edittype: "select", editoptions: { value: RetrievegridOperandList() } },
{ name: 'Value1', index: 'Value1', align: 'center', width: 40, editable: true },
{ name: 'AndOr', index: 'Refer', align: 'center', width: 80, editable: true, edittype: "select", editoptions: { value: "AND:And;OR:Or" } },
{ name: 'Operand2', index: 'Operand2', align: 'center', width: 80, edittype: "select", editable: true, editoptions: { value: RetrievegridOperandList() } },
{ name: 'Value2', index: 'Value2', align: 'center', width: 40, editable: true }],
root: 'rows',
row: 'row',
celledit: true,
sortname: 'ShortName',
sortorder: 'asc',
viewrecords: true,
gridview: true,
height: "100%",
rowNum: 10,
onSelectRow: function (id) {
if (id && id !== lastsel2) {
jQuery('#MultiCount').jqGrid('editRow', id, true);
jQuery("#MultiCount").jqGrid('saveRow', lastsel2, true);
lastsel2 = id;
}
}
});
}
