jqgrid apply filter after reload? - jqgrid

Question

Am using jqgrid, loading data once, sorting and filtering locally and doing a refresh after each update/insert/delete. It works fine, besides that if I am using a filter (on top of grid), the filter remains the same after refresh, but the filter is not re-applied on the newly loaded data.
I have tried to call mygrid[0].triggerToolbar() after reloading grid with trigger('reloadGrid'), but there is no effect.
Thanks for any help or pointers :-)
Code below:
var lastsel;
var mygrid;
var currentLang;
//setup grid with columns, properties, events
function initGrid(lang, productData, resellerData, resellerSearchData) {
mygrid = jQuery("#list2").jqGrid({
//data loading settings
url: '/public/Gadgets/LinkGadget/ProductLinks/' + lang,
editurl: "/public/Gadgets/LinkGadget/Edit/" + lang,
datatype: "json",
mtype: 'POST',
jsonReader: {
root: "rows",
cell: "",
page: "currpage",
//total: "totalrecords",
repeatitems: false
},
loadError: function (xhr, status, error) { alert(status + " " + error); },
//column definitions

}
//Used by initGrid - reloads grid
function reload() {
//jqgrid setting "loadonce: true" will reset datatype from json to local after grid has loaded. "datatype: local"
// does not allow server reloads, therefore datatype is reset before trying to reload grid
$("#list2").setGridParam({ datatype: 'json' }).trigger('reloadGrid');
//mygrid[0].clearToolbar();
lastsel = null;
//Comments: after reload, toolbar filter is not applied to refreshed data. Tried row below without luck
//mygrid[0].triggerToolbar();
}
//after successful save, reload grid and deselect row
function afterSave() {
reload();
}

Your data is not getting re binded to the grid after save/update delete
