[disabled] is ignored

[Deimoslink]

"@angular/core": "^5.2.3",
"ngx-select-ex": "^3.5.3"

<p>{{disabled}}</p>
<ngx-select [items]="items"
            [(ngModel)]="itemId"
            [disabled]="disabled"
            [placeholder]="placeholder"
            (selectionChanges)="itemSelected($event)">
</ngx-select>

disabled style is applied to select, but it is still clickable, thus it is still enabled

Thanks. I'll check this case.
