fixed the disabled state

[linusbrolin]

The disabled state wasn't working, due to the boolean used in the template only being a setter, not a getter.
Replaced with the private _disabled boolean instead.

@linusbrolin can not agree,
can you just add getter for disabled?
because switching to _disabled removes call to .hideOptions

[linusbrolin]

Sure.
I just thought that the public disabled should only be a setter.
But if having a public getter is no problem, then I'll do that instead, no problem. :)

status on this?

Thanks, sorry for delay
