如何在角度ng-repeat中绑定kendo下拉列表？

Question

实际上我想根据添加添加相同的下拉值。但是这里添加相同的下拉菜单，但是当我更改一个下拉列表时，它会同时更改所有下拉列表。

请帮助我解决这个问题。

HTML代码：

<div ng-repeat="serviceItems in serviceParameters | filter: headerFilter track by $index">
  <div class="row service-param-row">
    <div class="col-md-6 col-xs-12  col-sm-6 col-lg-6">
      <label class="col-lg-2 col-md-2 col-xs-12  col-sm-12">Header</label>
      <label class="col-lg-2 col-md-2 col-xs-12  col-sm-12">
        			    <input type="text" placeholder= "key"  ng-model="serviceItems.labelName">
        			</label>
      <label class=" col-lg-1 col-md-1 col-xs-12  col-sm-12">    						   
        			    <label class="label label-info">{{serviceItems.paramTypeValue}}</label>
      </label>
      <label class=" col-lg-3 col-md-3 col-xs-12 col-sm-12">    						   
        			    <select  k-option-label="'--Select Type--'" kendo-drop-down-list ng-model="adapterServiceFormData.headertype"  k-options="headertypelist" tabindex="6" ></select>				    						
        			</label>
      <label class="col-lg-3 col-md-3 col-xs-12  col-sm-12">  
        			    <kendo-button  ng-click="removeServiceParameter()" type="button" class="cancel">
                            <span class="k-icon k-i-cancel"></span>
        				 </kendo-button>
        			</label>
      <span ng-show="$last"> 
        			    <kendo-button  ng-click="addServiceParameter('', 'Header', '378e04cf-3124-44eb-86df-095bb08abc10')"><span class="k-icon k-i-plus"></span></kendo-button>
      </span>
    </div>
  </div>
</div>
