Bug on change ng-disable when using Multiple Select

[Vn-ChemGio]

Hello every body
I'm using ui-select on my project
But I have some problem:
When after select any item in ui-select-choices, I want temporary disable multiple select an display some input fields for user input (required)
But it's disabled only but not hidden or if I not click Outside To Close
I had been used:

{{$item.name}} -{{$item.reward}}

email: {{person.email}} age:

Selected: {{multipleDemo.selectedPeopleWithGroupBy}} -- {{counter}}

After select, I using onSelectCallback to disable box...
