That I have some group of checkbox I have used , through that when I used to get a value it's getting an "undefined", plz suggest me - am I using a correct format or not. I am new in angularjs, thank you.

In the HTML: 

```
<tbody>
   <tr data-skin="">
      <td align="center">
         <input type="checkbox" name="radio" class="check" value="1" ng-model="bnnrdata.bannerval.1">
      </td>
      <td style="text-align:center">
         <img src="~/Content/Tulips.jpg" width="180" height="80" />
      </td>
   </tr>
   <tr>
      <td style="visibility:hidden"> ddd</td>
   </tr>
   <tr data-skin="">
      <td align="center">
         <input type="checkbox" name="radio" class="check" value="2" ng-model="bnnrdata.Banner.2">
      </td>
      <td style="text-align:center">
         <img src="~/Content/Desert.jpg" width="180" height="80" />
      </td>
   </tr>
   <tr>
      <td style="visibility:hidden"> ddd</td>
   </tr>
   <tr data-skin="">
      <td align="center">
         <input type="checkbox" name="radio" class="check" value="3" ng-model="bnnrdata.Banner.3">
      </td>
      <td style="text-align:center">
         <img src="~/Content/Lighthouse.jpg" width="180" height="80" />
      </td>
   </tr>
   <tr>
      <td style="visibility:hidden"> ddd</td>
   </tr>
   <tr data-skin="">
      <td align="center">
         <input type="checkbox" name="radio" class="check" value="4" ng-model="bnnrdata.Banner.4">
      </td>
      <td style="text-align:center">
         <img src="~/Content/Penguins.jpg" width="180" height="80" />
      </td>
   </tr>
</tbody>
<div class="form-group" align="center">
   <button  ng-click="savebnnr()" ng-controller="bannerCtrl" class="btn btn-danger btn-sm">Skip & Continue..!</button>
</div>

```

In the AngularJS controller

```
angular.module('applictionmodule').controller("bannerCtrl", function ($scope, $http, InstanceService) {
    $scope.bnnrdata = {
        Banner: ''
    }
    $scope.savebnnr = function () {
        InstanceService.addinstance($scope.bnnrdata);
        $location.path('/Amminit');
    }
});

```
