jqGrid - Keep checkbox selected on grid reload when editing form

Question

I have a form that utilizes jqGrid to display personalized info for the user to select from. Everything works fine however on the "Review" page there is an option to edit the form. When you click edit and go back into the form selections all values selected are retained except for the jqGrid portion of the form that uses the checkbox values. How can I have this value retained so the user doesn't have to make the selection again?

var myGrid;
var blnListsFound = true;
var blnGridLoading = false;

function fnInitialize() {
    // Initialize the screen
    fnLoadForm();

    $('#no_transactions').hide();

    // alert("fnInitialize(): JS loaded fine, no errors");
}

function fnACHSwapGetGrid() {
    blnListsFound = true;
    // make sure we have a from account

    if ($('#selFromAccount').val() == '0') {
        return;
    }


    $('#imgWaitselFromAccount').show(); // show loading icon

    var urlString = '';
    var urlParams = new Array();
    // urlParams['rc'] = escape($('#RC').val());
    urlParams['RC'] = escape($('#txtMenuRC').val());
    urlParams['acctNBR'] = escape($('#selFromAccount').val());

    // get application type from aryAccount
    for (act in aryAccount)     {
        if (aryAccount[act]['Number'] == urlParams['acctNBR']) {
            urlParams['Appl'] = aryAccount[act]['Application'];
            break;
        }
    }

    $.jgrid.gridUnload("#list");

    myGrid = $("#list").jqGrid({
