Javascript 安格拉斯<；数据列表>；给出奇怪的选择

我正在尝试转换以下内容：

<td class="col-md-2">
<select style="max-width:120px" 
        ng-model="row.gaProfileId" 
        ng-repeat="profile.id as weGaAdminCtrl.showProfile(profile) for profile in weGaAdminCtrl.profiles"
        ng-change="weGaAdminCtrl.assignBrandToProfile(row)">
        </select>
</td>

变成这样：

<td class="col-md-2">
      <input type="text" list="datalist">
      <datalist id="datalist">
        <select style="max-width:120px;" 
                ng-model='row.gaProfileId' 
                ng-options='profile.id as weGaAdminCtrl.showProfile(profile) for profile in weGaAdminCtrl.profiles'
                ng-change="weGaAdminCtrl.assignBrandToProfile(row)">
        </select>
      </datalist>
</td>

我得到的是：

现在我不明白的是它如何给我“字符串：####”。有人知道我如何更改此设置吗？
