Collides with Ember's built-in `on` and `off` methods

[ef4]

Ember.Component has methods named on and off, which x-toggle is attempting to reuse for its own purposes. This fails in confusing ways on some versions of Ember. For example, using Ember 1.13 with x-toggle 0.5.10, the defaults provided in x-toggle are ignored and you end up trying to do indexOf on function values.

Good catch. Will change and release a major version, so it doesn't break anything for those that it works for. Does that sound fine to you?

Yes, makes sense. The names were public API, so a major rev is appropriate.

I just realized that my workaround for #40 was exacerbating this issue. I was using the XToggle class from the addon directory, and I missed that defaults only get set in the extended class in the app tree.

(It's still bad to squash on and off, but the squashing does actually work once I figured out why I had no default values.)

I will still change this and release a new version.
