JSAPI 4.x - Push query results to a FeatureForm?

[luckachi]

I haven't been able to find any examples of this or anything similar but I am wondering if it is possible to push query results to a feature form. What I need to have happen is when someone selects a species from a dropdown within the feature form it will populate 3 fields with information that is queried from a table (Genus, Species and USDA Plant Code). I have the query working and it returns the fields in the console but I don't quite know how to take those results and populate the feature form. Below is what I have now... also, I see that the "value-change" event for the feature form can be set on a specific field but there is no example of how that should look? In reality, I would only like this to occur when the "COMMON" field dropdown is modified.

I am using this example (https://developers.arcgis.com/javascript/latest/sample-code/editing-applyedits/)

What I have below is currently not working.

// Highlights the clicked feature and display
        // the feature form with the incident's attributes.
        function selectFeature(objectId) {
          // query feature from the server
          obsLayer.queryFeatures({
              objectIds: [objectId],
              outFields: ["*"],
              returnGeometry: true
            }).then((results) => {
              if (results.features.length > 0) {
                editFeature = results.features[0];

                // display the attributes of selected feature in the form
                featureForm.feature = editFeature;
                console.log("populate form");

                //**testing**
                //this query is performed when the selection changes on anything.
                //Returns the correct information
                featureForm.on("value-change", () => {
                  var featureAtt = featureForm.getValues();
                  var attributesSpecies = Object.entries(featureAtt).map(([key, value]) => ({key,value}));
                  var speciesID = attributesSpecies[9].value;
                  var speciesQuery = speciesTable.createQuery();
                  //speciesQuery.objectIds = [objectId];
                  speciesQuery.outfields = ["*"];
                  speciesQuery.returnGeometry = false;
                  speciesQuery.returnDistinctValues = true;
                  speciesQuery.where = "ID = " + speciesID + "";
                  //console.log(speciesQuery);
                  speciesTable.queryFeatures(speciesQuery).then(function(results){
                    var attributeArray = new Array();
                    results.features.forEach(function(item) {
                      attributeArray.push(item.attributes);
                    });
                    //console.log(attributeArray[0].GENUS);
                    var attr = [];
                    attr["GENUS"] = attributeArray[0].GENUS;
                    attr["SPECIES"] = attributeArray[0].SPECIES;
                    attr["PLANTCODE"] = attributeArray[0].PCODE;
                    console.log(attr);
                    editFeature.attributes.GENUS = attributeArray[0].GENUS,
                    editFeature.attributes.SPECIES = attributeArray[0].SPECIES,
                    editFeature.attributes.PLANTCODE = attributeArray[0].PCODE
                  })
                });
                //**end testing**

                // highlight the feature on the view
                view.whenLayerView(editFeature.layer).then((layerView) => {
                  highlight = layerView.highlight(editFeature);
                });
              }
              console.log(editFeature);
            });
        }

In case anyone else is trying to do something similar,

I solved this by replacing this in my original code :

editFeature.attributes.GENUS = attributeArray[0].GENUS,
editFeature.attributes.SPECIES = attributeArray[0].SPECIES,
editFeature.attributes.PLANTCODE = attributeArray[0].PCODE

with this: 

featureForm.viewModel.setValue("GENUS", attributeArray[0].GENUS);
featureForm.viewModel.setValue("SPECIES", attributeArray[0].SPECIES);
featureForm.viewModel.setValue("PLANTCODE", attributeArray[0].PCODE);
