单选按钮事件未第二次触发

我有两个单选按钮。1.员工2客户，当我必须选择员工时，员工ID文本框应该打开n我单击客户时，它应该消失。当我第一次点击它时，它第二次正常工作了，但是没有工作。

HTML文件

   <div class="row control-group">
             <label >
                     <input name="cssPre" id="css1" value="geEmp" class="input-xlarge" type="radio" data-ng-model="addUser.Emp" ng-change="ge()">{{::'label.addUser.employee'|translate}}
            </label>

        <label >
        <input name="cssPre" id="css2" value="customer" type="radio" data-ng-model="addUser.customer" ng-change="customer()">{{::'label.addUser.Customer'|translate}}
         </label> 

我想展示的文字框

<div ng-show="ge == true">
        <div class="row control-group"  ng-show="addUser.geEmp" ng-class="{error:addUserForm.phone.$dirty && !addUserForm.phone.$valid &&  !addUserForm.phone.$error.pattern, success:addUserForm.phone.$valid}">
               <label class="col-xs-4 col-sm-4 col-md-3 col-lg-3 control-label">{{::'label.addUser.SSO'|translate}}</label>

               <div class="col-xs-7 col-sm-7 col-md-9 col-lg-9 controls">
                  <input type="text"

                         class="input-xlarge"
                         id="sso"
                         name="phone"
                         ng-model="addUser.user.phone"
                         ng-pattern="ph_numbr"
                         placeholder="{{::'placeholder.addUser.phone'|translate}}"
                         ng-change="addUserForm.phone.$setValidity('duplicateName', true);"
                         required="true"
                         ng-maxlength=8
                         ng-minlength=8
                         ge-auto-focus
                        />

                  <span class="help-block" ng-show="addUserForm.phone.$dirty && addUserForm.phone.$error.required">{{::'error.required'|translate}}</span>
                   <span class="help-block" ng-show="addUserForm.phone.$dirty && addUserForm.phone.$error.pattern">{{::'error.number'|translate}}</span>
                  <span class="help-block" ng-show="addUserForm.phone.$dirty && addUserForm.phone.$error.maxlength">{{::'error.max.length'|translate}}</span>
                  <span class="help-block" ng-show="addUserForm.phone.$dirty && addUserForm.phone.$error.duplicateName">{{::'error.editOrganization.duplicateName'|translate}}</span>
               </div>
            </div>
