AngularJS cannot pass $ index from modal loading window

I bang my head on the wall here. I use ng-repeat to populate the table. Inside each line there are two buttons, one for updating the contents of the line and for downloading files. The "Download" button opens a modal download window, in which the user selects files and clicks the "Send" button.

The submit button uses ng-click to launch a function that uses the $ index as parameter. But the value of $ index is always the same no matter which row is selected.

I do not understand that I use the same syntax (albeit outside the modal window) on my update button, which works fine.

HTML:

<tr ng-repeat="item in items | filter:search " ng-class="{'selected':$index == selectedRow}" ng-click="setClickedRow($index)">
   <td>{{$index}}</td>
   <td ng-hide="idHidden" ng-bind="item.Id"></td>
   <td ng-hide="titleHidden">
      <span  data-ng-hide="editMode">{{item.Title}}</span>
      <input  type="text" data-ng-show="editMode" data-ng-model="item.Title" data-ng-required />
   <td> 
      <button type="button" class="btn btn-primary uploadBtn" data-ng-show="editMode" data-toggle="modal" data-target="#uploadModal">Upload file  <i class="fa fa-cloud-upload"></i></button>
      <!-- Upload Modal -->

$scope.updateItem = functon(index)
{
$scope.tempVar = index;
}

now use the value of tempVar in you function 

 $scope.uploadAttachment = function executeUploadAttachment(index, type) {
var index = tempVar;            //assign the value of tempvar to index
var listname = "Risk Register";
var id = $scope.items[index].Id;
console.log(indexID);
readFile("uploadControlId").done(function(buffer, fileName) {
    uploadAttachment(type, id, listname, fileName, buffer).done(function() {
        alert("success");
    }).fail(function() {
        alert("error in uploading attachment");
    })
}).fail(function(err) {
    alert("error in reading file content");
});
