Update form in meteor using autoform - mongodb

Question

I have a collection that handles default values for forms. I need to build a UI to update the default values themselves, instead of force updating via mongo backed.
I've used aldeed's update-each functionality. The data is being fetched from the DB and displayed in the table. However, when I try to update by inputting new values in the textbox, it does not persist. In fact, it keeps throwing this error which i'm not aware of.
Exception in template helper: TypeError: Cannot read property 'namedContext' of undefined
at Object.autoFormFieldIsInvalid
As a sample, here is what I'm working with:
Mongo Collection:
meteor:PRIMARY> db.testCollection.find()
{ "_id" : ObjectId("577ccd87f57f43d790c3ec49"), "schemaName" : "test_schema", "label" : "test_lable", "value" : "test_value" }
Schema:
test_schema = new SimpleSchema({
"schemaName": {
type: String,
},
"label": {
type: String,
},
"value": {
type: String,
}
});
testCollection.attachSchema(test_schema);
Template:
<template name = "testTemplate">
<table class="table table-bordered table-condensed">
<thead>
<tr>
<td style="width: 85px">Schema Name</td>
<td style="width: 85px">Label</td>
<td>Default Value</td>
<td style="width: 250px">New Default Value</td>
</tr>
</thead>
<tbody>
{{#each items}}
<tr>
<td>{{this.schemaName}}</td>
<td>{{this.label}}</td>
<td>{{this.value}}</td>
<td>
{{#autoForm id=updateDefaiultsID type="update" collection=testCollection doc=this autosave=true}}
{{> afFormGroup name="value" label=false}}
{{/autoForm}}
</td>
</tr>
{{/each}}
</tbody>
</table>
</template>
Helper
import { Template } from 'meteor/templating';
import '../templates/testTemplate.html';
if (Meteor.isServer) {
Meteor.publish(null, function () {
return testCollection.find();
});
testCollection.allow({
update: function () {
return true;
}
});
}
else if (Meteor.isClient) {
Template["testTemplate"].helpers({
items: function () {
return testCollection.find({}, {sort: {name: 1}});
},
updateDefaiultsID: function () {
return "testTemplate" + this._id;
}
});
}

Change this
from
<td>{{this.schemaName}}</td>
to
<td>{{this.schema_name}}</td>
