Visibility On-Off of Label Layer in arcgis javascript 3.7

Question

I am using ArcGIS JavaScript 3.7 API's and i am using agsjs.dijit.TOC control and it is working fine but when i added Label Layer in my map that time Label layer is coming fine but TOC is not working Properly.

While Pressing the checkbox to On-Off the Layer it is working fine but regarding the feature layer i added one Label layer that is not getting On-Off

Can anyone tell me how to Switch-Off or On the Label Layer.

Thanks in Advance.

I am Pasting some code..

 Var load = function () {
 require(["dojo/_base/Color", "esri/symbols/TextSymbol", "esri/renderers/SimpleRenderer", "esri/renderers/ScaleDependentRenderer"],
 function (Color, TextSymbol, SimpleRenderer, ScaleDependentRenderer) {
 var statesColor = new Color("#666");
 var fieldLabel = new TextSymbol().setColor(statesColor);
 fieldLabel.font.setSize("4pt");
 fieldLabel.font.setFamily("arial");
 statesLabelRenderer = new SimpleRenderer(fieldLabel);
 return statesLabelRenderer;
 });
 }
 var layers = []; 
 var layer = new esri.layers.FeatureLayer(url, {
 mode: esri.layers.FeatureLayer.MODE_ONDEMAND,
 outFields: ["*"] 
 });
 layers.push(layer);
 layerInfo.push({ layer: layer, title: item["LookupDisplayDesc"], boxLabel: item["LookupDisplayDesc"], id: layer.id, checked: layer.visibleAtMapScale, slider: true });
if (item["LookupLongDesc"] != null && item["LookupLongDesc"] != "") {
 var fieldNames = item["LookupLongDesc"].split(",");
 var labelFields = "";
for (var i = 0 ; i < fieldNames.length ; i++) {
 labelFields = labelFields + "${" + fieldNames[i].trim() + "},";
}
 labelFields = labelFields.slice(0, -1).trim();
 load();
 var labelLayer = new esri.layers.LabelLayer();
 labelLayer.addFeatureLayer(layer, statesLabelRenderer, labelFields);
 layers.push(labelLayer);
 }
}
map.addLayers(layers);
 dojo.connect(map, 'onLayersAddResult', function (results) {
 if (layerInfo.length > 0) {
 var legendDijit = new esri.dijit.Legend({
 map: map,
 layerInfos: layerInfo
 }, "legendDiv");
 legendDijit.startup();
 }
 toc = new agsjs.dijit.TOC({
 map: map,
 layerInfos: layerInfo
 }, 'LayerDiv');
 toc.startup(); 
 });

U can achieve it, by simply adding a id to the LabelLayer:

 var labelLayer = new esri.layers.LabelLayer({ id: "labels" });

And then get the layer from the id, and set the visibility:

map.getLayer("labels").setVisibility(false/true);
