Angularjs ui-select несколько фильтр повторения нг

Question

У меня есть проблема с UI-Select Multiple в AngularJs. Дело в том, что я не могу правильно отфильтровать список с помощью ng-repeat. У меня есть список музыкальных инструментов, список стран и поисковый запрос, соответствующий компании.

Вот мой код:

<div class="filter-container pull-left">

      <div>

        <span>Instrument</span>

        <div class="form-group">
          <ui-select class="input-search" multiple ng-model="instrument.selected" theme="bootstrap" ng-disabled="disabled" close-on-select="false" title="Select instruments">
            <ui-select-match placeholder="Select instruments...">{{$item.name}}</ui-select-match>
            <ui-select-choices repeat="instrument.value as instrument in instruments | filter: $select.search">
              {{instrument.name}}
            </ui-select-choices>
          </ui-select>
        </div>

        <span>Country</span>

        <div class="form-group">
          <ui-select class="input-search" multiple ng-model="country.selected" theme="bootstrap" ng-disabled="disabled" close-on-select="false" title="Select countries">
            <ui-select-match placeholder="Select countries...">{{$item.name}}</ui-select-match>
            <ui-select-choices repeat="country.code as country in countries | filter: $select.search">
              {{country.name}}
            </ui-select-choices>
          </ui-select>
        </div>

        <span>Company</span> 
        <div class="form-group mbl">
          <label for="company" class="sr-only">Company</label>
          <input id="company" ng-model="company.selected" type="text" value="" placeholder="Search..." class="form-control">
        </div>
      </div>            
    </div>


      <!-- <div class="clearfix"></div> -->

      <div style="width:75%; float:right;">

        <div class="results-container">
          <span><strong class="text-info">{{auditions.length}}</strong> auditions</span>
        </div>

        <ul class="ul-nostyle">
          <li ng-repeat="audition in auditions">
            <div>            
              <div class="pull-left">
                <span class="label label-info">{{audition.instrument}}</span> <span class="label label-info"><img src="img/flags/{{audition.country}}.gif" class="flag">{{audition.country}}</span>
              </div>
              <div class="pull-right">
                <button class="btn btn-social-facebook">
                  <span class="fui-facebook"></span> 500
                </button>
                <button class="btn btn-social-facebook">
                  <span class="fui-user"></span> 500
                </button>
              </div>
              <div class="clearfix"></div>
              <div class="pull-left">
                <small><strong>Closing date:</strong> {{audition.closingDate}}</small>
              </div>
              <div class="clearfix"></div>
              <div>
              <p><strong>{{audition.company}}</strong></p>
              <p class="title"><strong>{{audition.title}}</strong></p>
              <p class="content">{{audition.description}}</p>
              </div>
              <div class="pull-right">
                <a href="{{audition.url}}" class="btn btn-link">More information</a>
              </div>
              <div class="clearfix"></div>                  
            </div>
          </li>

И моя модель (я не включаю все страны...):

 $scope.audition = [];
 $scope.auditions = [
