Angular checkbox filter works reversed

Have an object list

JS:

$scope.datas = [
        {date:'06-12-2016', name : 'Pinao Class', state: 'archived', remark : 'remarled', amount : 101, id : 21},
        {date:'15-04-2016', name : 'drivers Class', state: 'notarchived', remark : 'remarled', amount : 102, id : 22},
        {date:'24-03-2016', name : 'Airplane Class', state: 'archived', remark : 'remarled', amount : 103, id : 23},
        {date:'28-02-2016', name : 'burger Class', state: 'notarchived', remark : 'remarled', amount : 104, id : 24},
         {date:'28-02-2016', name : 'burger Class1', state: 'notarchived', remark : 'remarled', amount : 104, id : 241},
          {date:'28-02-2016', name : 'burger Class2', state: 'notarchived', remark : 'remarled', amount : 104, id : 2432},
           {date:'28-02-2016', name : 'burger Class3', state: 'notarchived', remark : 'remarled', amount : 104, id : 2342},
            {date:'28-02-2016', name : 'burger Class4', state: 'archived', remark : 'remarled', amount : 104, id : 2443},
             {date:'28-02-2016', name : 'burger Class5', state: 'archived', remark : 'remarled', amount : 104, id : 2243},
              {date:'28-02-2016', name : 'burger Class6', state: 'archived', remark : 'remarled', amount : 104, id : 2242},
  ];

  $scope.paymentList = $scope.datas;

Have a filter using checkbox. The idea is to show all items with State:archived

My HTML :

<th><input ng-model="archived.state"  type="checkbox"
      ng-true-value="'notarchived'" ng-false-value="undefined">Show archived</th>

<tr  ng-repeat="paymentinfo in paymentList | filter:keyword | filter:money | filter:getdate | filter:{state: archived.state}">
          <td></td>
          <td ng-click="singlepage(paymentinfo.id)" ><a></a> </td>
                  <td>
                      <div class="grey-flag remark-payment">
                          <div class="hover-remark"></div>
                      </div>
                  </td>
</tr>

Filter works reverse. When I check. show all notarchived elemets. need to show archived. When write like that

filter want's working work when I write just "archived" and it works when I write "notarchived", but it works reverse.
