Does not work: {{ some-component disabled=(not someModel.isDirty) }}

So I'm trying to use ember-truth-helpers with this addon: ember-cli-async-button.

It is a simple component that has a disabled property bound to an attribute.

This works as expected:

Component disabled: {{ async-button disabled=true }}
Component disabled: {{ async-button disabled=(not false) }}

Component enabled: {{ async-button disabled=false }}
Component enabled: {{ async-button disabled=(not true) }}

Bot then I've got an Ember Data model. This also works fine:

Displays "false" or "true": {{ model.isDirty }}

Component enabled or disabled depending on `isDirty` state:
{{ async-button disabled=model.isDirty }}

Now, i'm putting model.isDirty into the not subexpression, and suddenly it's not working!

Displays "false" or "true": {{ model.isDirty }}

Component always enabled, regardless of `isDirty` state:
{{ async-button disabled=(not model.isDirty) }}

I'll take a look..

I see you've got:

Displays "false" or "true": {{ model.isDirty }}

Try also adding:

Displays "false" or "true": {{ not model.isDirty }}

Make sure that displays what you expect.. It will narrow down the issue a bit more

{{ not model.isDirty }} works as expected.

I have experienced the same problem with an if subexpression, without ember truth helpers.

And I was unable to reproduce the problem with a blank component.

Looks like it's a problem of ember-cli-async-button.
