disabled on item not working

[galvakojis]

https://stackblitz.com/edit/ngx-select-ex-issues-100-uezwvq?file=app/app.component.ts

expected behavior:
after selection an item in "a", in "b" that item should be disabled

looks like [items] array is not refreshing after changes

@galvakojis Try it: https://stackblitz.com/edit/ngx-select-ex-issues-100-eddq5b

it is working... but then how about vice versa?
when something is selected on "b" it needs to disabled on "a"

@galvakojis It was just an example, not perfect but shows an idea.

@optimistex Konstantin Polyntsov:
If you want you can try to improve the component. I'll publish it as a dev branch. Better to make tests.
I would help you but I'm too busy right now.
If you consider to maintain then feel free to ask me

@optimistex
i think the problem is with item differs(?) it should check changes of object properties also

@galvakojis Probably it is because of:

ngx-select-ex/src/app/lib/ngx-select/ngx-select.component.ts

Line 38 in 0d7e08f

changeDetection: ChangeDetectionStrategy.OnPush,

It was added by one of maintainers for some performance.
So, probably we need use a code like this:

ngx-select-ex/src/app/lib/ngx-select/ngx-select.component.ts

Line 203 in 0d7e08f

this.cd.markForCheck();

Unfortunately, I have no so much time to investigate it for now.
It would be cool if you'll found some time to fix it.
