Adding feature layer to existing web map

I'm having an issue adding a feature layer to an existing webmap. Here's what I'm trying to accomplish.

I'm building a feature layer from a feature collection. The attributes for the feature collection is coming out of a different service then arcgis server, (just a database table). When building up the feature collection, It keeps shooting me in the foot saying no object id. So I went ahead and told it to use a different field for the object id. here's a code snippet of my feature collection:

var featureCollection = {

"layerDefinition": null,

"featureSet": {

"features": [],

"geometryType": "esriGeometryPolygon"

}

};

featureCollection.layerDefinition = {

"geometryType": "esriGeometryPolygon",

"objectIdField": "accountNumber",

"fields": [{

"name":"routingNumber",

"alias": "Routing Number",

"type":"esriFieldTypeString"

{

"name":"accountNumber",

"alias": "Account Number",

"type":"esriFieldTypeInteger"

{

"name":"sidwellNumber",

"alias": "Parcel Number",

"type":"esriFieldTypeString"

}],

};

Now I'm getting/building up the attributes and adding them to the features array with these methods:

var featureLayer = new FeatureLayer(featureCollection,{

id: 'Ratio Viewer Results',

mode: FeatureLayer.MODE_ONDEMAND,

infoTemplate: new PopupTemplate({

accountNumber: "{accountNumber}",

routingNumber: "{routingNumber}"

})

});

this.map.on("layer-add-result", function(){

requestLayerData();

});

this.map.addLayer(featureLayer);

featureLayer.on("edits-complete", function(results){

console.log("Edits complete results: ", results);

});

function requestLayerData(){

request.post("URL to service", {

data: JSON.stringify(searchParams),

headers: {

"Content-Type": "application/json"

handleAs: 'json'

}).then(requestSucceeded)

.catch(requestFailed);

}

function requestSucceeded(response){

var features = [];

arrayUtils.forEach(response, function(item){

var attributes = {

"accountNumber": item.accountNumber,

"routingNumber": item.routingNumber,

"sidwellNumber": item.sidwellNumber,

};

var geometryQuery = new Query();

var geometryQueryTask = new QueryTask("URL to arcgis service");

geometryQuery.where = "MACCT = " + item.accountNumber;

geometryQuery.returnGeometry = true;

geometryQueryTask.execute(geometryQuery)

.then(function(geoData){

var geometry = {

"geometry": geoData.features[0].geometry,

"symbol": {

"color":[

"outline":{

"color":[

255

"width":1,

"type":"esriSLS",

"style":"esriSLSSolid"

"type":"esriSFS",

"style":"esriSFSSolid"

}

};

var graphic = new Graphic(geometry);

graphic.setAttributes(attributes);

console.log(graphic);

features.push(graphic);

}, function(error){

console.log("Error in feature set request: ", error);

});

featureLayer.applyEdits(features, null, null);

}

function requestFailed(error){

console.log("Main Request errored: ", error);

}

and when I add the callback function to applyEdits, the results there are blank. Plus i have the edit-complete event hooked to this feature layer, but it doesn't fire at all. Thoughts? Thanks in advance!

UPDATE -

It looks like it's being added as a graphics layer and not a feature layer? when I look at the map object, this layer isn't in the list of layerIds, but it's in the list of graphic layers. Not what I want. Any ideas?
