Replacing name in layers pane doesn't update

I have a script that searches for layer names and replaces them, so far it works fine. However I have run across a problem and I don't understand what is happening. I have altered the script to include certain objects (pathItems, etc), in addition to layers. However when it finds and replaces the object name (which it does find them), it does not update in the layers pane. I debugged the program and it does indeed find and replace it, but does not update the names in the layers pane of Adobe Illustrator.

#target illustrator
#targetengine main

// JavaScript Document
if (app.documents.length > 0) {
    var doc = app.activeDocument;
    var docLayers = doc.layers;
    var searchText = "";
    var replaceText = "";
    var found = false;
    var match = false;

    function replace(layers) {
        match = false;
        recurseLayers(layers);
        app.redraw();

        // When match is found, show dialog
        if (match) {
            alert("Found match!");

            match = false;
        } else {
            alert("No match found.");
            match = false;
        }
    }


    function recurseLayers(layers) {
        var length = layers.length;
        var currentLayer = null;
        var searchtext = searchText;
        var replacetext = replaceText;


        try {
            for (var i = length; i--;) {
                currentLayer = layers[i];
                var visible = checkLayerVisibility(currentLayer);
                var locked = checkLayerLocked(currentLayer);

                if (visible == true || locked == false) {
                    replaceName(currentLayer, searchText, replaceText);

                    if (currentLayer.layers) {
                        recurseLayers(currentLayer.layers);

        try {

            match = true;

    startGUI();

    function startGUI() {

        var win = new Window("dialog", "Replace Layer name", undefined);

        win.orientation = "column";

        // Search

        // Set first text box to active
        txt_searchText.active = true;

        function enter(k) {
            if (k.keyName == "Enter") {
                searchText = txt_searchText.text;
                replaceText = txt_replaceText.text;

} else {
        alert("You do not have any document opened!");
}

These are the layers I am using, the lines are what I need to replace, just their display name (either full name or part of the name).

As you can see in the second picture, the name has indeed been changed (changed the 'A8900' to '1'), but only shows in when I double click the name, or hide and unhide the layers (then it updates). I can't figure out why this is happening, maybe something to do with how the objects work in AI? There doesn't seem to be any way to debug this either, since in my code it working fine, but its not updating correctly in AI. I also used an 'app.redraw()' in the hopes that it will refresh it, but it does not. Any help is appreciated

Solution

I managed to get it working, I added a line of code to select the layer and it updates the name in the layers panel.

If anyone know why this happens, I would still like to know.

if (app.documents.length > 0) {
    var doc = app.activeDocument;

    var found = false;
    var match = false;

    function replace(layers) {
        match = false;
        recurseLayers(layers);

        // When match is found, show dialog
        if (match) {
            alert("Found match!");

            match = false;
        } else {
            alert("No match found.");
            match = false;
        }
    }


    function recurseLayers(layers) {
