设置AngularJs Selector

Question

当我尝试在angularJS选择器中设置初始值时，它会返回＆＃34;空白＆＃34; 元素，其值为"<option value="? number:1000139 ?">

如何设置默认值，而不会将其设置为某些乱码。

我的选择器如下所示：

<select ng-model="dataToCheckForImport.importContractId" ng-init="dataToCheckForImport.importContractId=opt.selectedContract">
   <option ng-selected="{{option.contract.kontraktID == dataToCheckForImport.importContractId}}" value="{{option.contract.kontraktID}}" ng-repeat="option in opt.allContracts">{{option.contract.kontraktID}} </option>
   <option value="-1">In Column</option>
 </select>

这是我获得的输出：

我已经尝试将其设置为字符串，这只会使我的输出具有＆＃34;字符串格式＆＃34;比如"<option value="? string:1000139 ?">

我做错了什么？

Anyone finding this, the problem is when types do not match each other. in my example i tried to initialize my selector with a string and not a number as every other option is a number. Making all value "strings" solved my problem. also covered in this question:
