Re-Expand rows after a page refresh

Eldorado

Hey guys, looking for some help with making my rows auto-expand to the same state they were in after a page refresh is done

I'm using datatables to display data from a number of SharePoint lists using the rest api to pull the data, when a row is expanded then more data is pulled and displayed for the detail, as part of this detail is a Status field which I am allowing the user to click on which opens a SharePoint model dialog edit form where they can edit the value as well as enter a couple other pieces of information

My issue is that when the form is then closed the data showing does not reflect any updates that were made to that Status field, I have considered inline editing but then the user would not have the ability to enter/edit the other fields that are only shown in the dialog box, displaying them inline is not an option as it would clutter the screen, so I am now trying to do a page refresh and automatically re-open any rows that were already open..

Maybe this is too much trouble? Is it possible to automatically close/re-open a row?

Below is my code (hopefully I'm formatting this post correctly for it to display), I am attempting to use the html5 localStorage functionality to save data between page refreshes, my issue comes when I retrieve the data I stored in anOpen after the refresh in the "fnDrawCallback" function... which I'm not sure is proper either

var anOpen = [];

$(document).ready(function() {

   
    var call = $.ajax({
        url: "/_vti_bin/ListData.svc/TestRuns?$expand=TestCases,TestSuites",
        type: "GET",
        dataType: "json",
        headers: {
            Accept: "application/json;odata=verbose"
        }
   
    });

    call.done(function (data,textStatus, jqXHR){

        var trData = data.d.results;
        var oTable = $('#trTable').dataTable({
            "bDestroy": true,

                {
                    openObject = retrievedObject.split(",");
                    localStorage.clear('anOpenObject');                
                    
                    $.each( openObject, function ( i, id ) {
                        $('#'+id+' td:first-child').trigger( 'click' );
