What might be causing the ng-model in this plunkr to not update as expected?

I recently customized a ui-select plunkr to suit my specific needs. I've noticed that the ng-model is not updating as expected, but interestingly, clicking the button to update the model results in the ui-select getting updated.

Any guidance on resolving this issue would be greatly appreciated!

<h3>Custom Select Theme</h3>
<p>Chosen: {{id}}</p>
    <ui-select ng-model="id" theme="customSelect" style="min-width: 300px;">
      <ui-select-match placeholder="Choose a person from the list or search for their name/age...">{{$select.selected.email}}</ui-select-match>
      <ui-select-choices repeat="person.id as person in people.devs | filter: {email: $select.search, id: $select.search}">
        <div ng-bind-html="person.id | highlight: $select.search"></div>
        <small>
          <span ng-bind-html="''+person.id | highlight: $select.search"></span>
          {{person.email}}
        </small>
      </ui-select-choices>
    </ui-select>

<br>
<button class="btn btn-primary" ng-click="id = 2">Update Model</button>
<span>(id = 2) </span>

Issue with scope :

 <ui-select ng-model="$parent.id" ....>

To avoid encountering this issue, it is recommended to use dot notation and initialize variables in your controller by creating intermediary fields.

 // controller
 $scope.context = {id:-1};
 // html
  <ui-select ng-model="context.id"

This situation occurs frequently, as ng-if can lead to the same problem. This limitation is due to the constraints of JavaScript inheritance, which Angular is unable to address.
