从列表中保存在角度js中不起作用

Question

我在表中有一个重复的行。其中我有复选框列和文本列。我必须使用修改后的复选框保存整个重复列.List可以保持更改。但有时候保存功能会不是hit.can任何人帮助我做错了什么

  <tr ng-repeat="Screenrights in lstScreenAccessDetails">
                    <td class="txt-center" ng-bind="lstScreenAccessDetails[$index].ModuleName">
                    </td>
                    <td class="txt-center" ng-bind="lstScreenAccessDetails[$index].ScreenName">
                    </td>
                    <td class="txt-center">
                        <input type="checkbox" ng-model="lstScreenAccessDetails[$index].Create" />
                    </td>
                    <td class="txt-center">
                        <input type="checkbox" ng-model="lstScreenAccessDetails[$index].Edit" />
                    </td>
                    <td class="txt-center">
                        <input type="checkbox" ng-model="lstScreenAccessDetails[$index].Delete" />
                    </td>
                    <td class="txt-center">
                        <input type="checkbox" ng-model="lstScreenAccessDetails[$index].View" />
                    </td>
                </tr>
