Javascript Uso de <select> <option> com Angular

[Xandrules]

Boa Tarde,
estou com um problema em uma estrutura onde tenho um select e o mesmo com um input relacionado sendo assim eu posso mudar o value do meu option.
o problema e que quando eu mudo o input o label do meu option Some. Para carregar o valor estou usando o Angular, segue o trecho de codigo.

 

 <div class="col-sm-8">
                                    <div class="row">
                                      <div class="col-xs-6 col-sm-7 no-right-padding">
                                        <div class="input-group">
                                            <select ng-model="newStream.type"
                                                  name="type" class="form-control" required
                                                  ng-disabled="{{::auth.isGuest()}}"
                                                  >
                                             <option ng-repeat="item in streamsTypesOptions" value="{{::item.value}}">{{::item.name}}</option> 
                                          </select>
                                          <span class="input-group-addon">
                                            <button type="button" class="btn btn-box-tool" tooltip="Undo"
                                                    ng-click="newStream.type = currentEditStream.type"

                                      </div>
                                    </div>
                                  </div>

minha estrutura no ng-model e a seguinte.

 

$scope.newStream = [{

            name: "Audio",

            type: STREAM_TYPES.AUDIO,
            
            checked: 17
        }, {

            name: "Video",

            type: STREAM_TYPES.VIDEO,
            
            checked: 27
            
        }, {

            name: "Closed Caption",

            type: STREAM_TYPES.CLOSED_CAPTION,
            
            checked:6
        }, {
            name: "Others",

            type: STREAM_TYPES.OTHERS,
            
            checked: 0
           
        }];
