了解选择选项的ng模型

Question

我的控制器：

$scope.taglist = [{"name":"Fruit_Type","value":"0"},
                  {"name":"Leaves_Arrangment","value":"?"},
                  {"na‌​me":"Leaves_Margin","value":"?"},
                  {"name":"Leaves_Type","value":"?"}];

这是我的表格

<form id="filter_form" onchange="angular.element(this).scope().fileNameChanged(this)" novalidate class="simple-form">
  <div ng-repeat="(key, value) in tags.tags.objects | groupBy:'category.name'">
    <div class="item item-divider">
      {{ key }}
    </div>
    <label class="item item-input item-select" ng-repeat="(item_key, item) in value | groupBy:'subcategory.name'">
      <div class="input-label">
        {{ item_key }}
      </div>
      <select name="{{ key }}_{{ item_key }}" ng-model="taglist" ng-options="option.description for option in item">
        <option ng-value="">------</option>
      </select>
    </label>
  </div>
</form>
Currently selected: {{ taglist }}

目前选择的节目：

Currently selected: [{"name":"Fruit_Type","value":"0"},
                     {"name":"Leaves_Arrangment","value":"?"},
                     {"na‌​me":"Leaves_Margin","value":"?"},
                     {"name":"Leaves_Type","value":"?"}]

为什么不根据$ scope.taglist设置选项？我认为这应该发生的印象。 所以Fruit Type应该选择0，其余没有。

我只是试图让表格处于状态，因为标签列表位于
