Angular UI多个ui-select不起作用

Question

Angular UI中的多重选择 - 选择不起作用。这是我的例子：

 <ui-select multiple ng-model="params.filter()['manager']" class="form-control" reset-search-input="false">
                                <ui-select-match class="ui-select-match" allow-clear="true" placeholder="Manager">{{$select.selected.name }}</ui-select-match>
                                <ui-select-choices class="ui-select-choices" repeat="item.id as item in selectArray.managerArray  | filter: $select.search "
                                                   refresh="refreshItem($select.search, 'UserGetSearch', 'managerArray')"
                                                   refresh-delay="0">
                                    <div ng-bind-html="item.name"></div> 
                                </ui-select-choices>
                            </ui-select>
