ember hasDirtyAttributes do not work with object (json)

I have a model:

export default Model.extend({
  title: attr('string'),
  attributes: attr('jsonb')
});

Where attributes is a custom json filed stored as jsonb in Postgres.

let say:

{
"name":"Bob",
"city":""
}

So I can easily manipulate attributes using template
<form.element .. @property="attributes.city"/> or model.set('attributes.city','city name')

Problem: hasDirtyAttributes do not changing because technically we have old object. But when I try to copy object let say JSON.parse(JSON.stringify(this.get('attributes')) hasDirtyAttributes works as expected

So how to write some Mixin for a Model or other workaround which on the change of any attribute property will mark hasDirtyAttributes as true. I will update whole object so doesn't matter which property actually was changed.

Same problem: https://discuss.emberjs.com/t/hasdirtyattributes-do-not-work-with-nested-attributes-json-api/15592

existing solution doesn't work for me at all:

• ember-dirtier
• ember-data-relationship-tracker
• ember-data-model-fragments (a lot of changes under the hood and broke my app)
