autoValues don't go to a collection from standard 'insert' type of form

For insert type of form autoValues work in a client's console, but don't save to DB. And for update type of form they work fine though.

Worthwhile to note:

I don't attach any SimpleSchema to my form, just referencing to it via schema=stepSchema autoForm param instead. I tried to attach it, but it didn't help.
And I give a form both schema and collection params.

As a workaround now I use my own insert logics with onSubmit hook and normal type of form.

Here's a part of my SS:

Schema.wizardStep1 = new SimpleSchema({
  createdAt: {
    type: Date,
    autoValue: function() {
      if (this.isInsert) {
        return new Date();
      } else if (this.isUpsert) {
        return {$setOnInsert: new Date()};
      } else {
        this.unset();
      }
    },
  },
  owner: {
    type: String,
    autoValue: () => Meteor.userId()
  }
}, { tracker: Tracker })
