Ion-checkbox wrongly showing selected

Hello Everyone -

I have spent much time on the following issue with no luck, any help will be greatly appreciate -

In my app, I am trying to allow users select multiple image items and then delete all the selected items on the click of a button.
The problem I am facing is this -

When I select items and click on the delete button, it works fine and removes the selected items from the list/display, however, the next item in the list, the checkbox automatically shows pre-selected somehow. In reality the checkbox is not selected, because if I try to delete that item, it does not actually deletes it, but somehow the checkbox wrongly shows as selected on the UI.

Below is my sample code with the issue recreated -
steps to reproduce the issue -

  1. Select the first item checkbox.
  2. Click on the delete button.
  3. The result will be that the selected item is deleted correctly, however, the next item in the list will show checkbox as selected automatically, and that is the problem.

Controllers.js Code -

angular.module('starter.controllers', [])

.controller('MyCtrl', function($scope) {

$scope.imageUrls = [];
            uri: "",
            desc: "First",
            price: "",
            isClicked: false

            uri: "",
            desc: "Second",
            price: "",
            isClicked: false

            uri: "",
            desc: "Third",
            price: "",
            isClicked: false
            uri: "",
            desc: "Third",
            price: "",
            isClicked: false

$scope.checkSelect = function(index)

  console.log('array index is '+index);
      var currentItem = $scope.imageUrls[index];
        currentItem.isClicked = false;
        currentItem.isClicked = true;

$scope.delete = function()
for(var i=0;i<$scope.imageUrls.length;i++)
                var item = $scope.imageUrls[i];
                var elementChecked = item.isClicked;
                console.log('elementChecked is - '+elementChecked+ ' at index '+i);

App.js code -

angular.module('starter', ['ionic', 'starter.controllers'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
    // for form inputs)
    if (window.cordova && window.cordova.plugins.Keyboard) {
    if (window.StatusBar) {
      // org.apache.cordova.statusbar required

So this seems to be an issue with collection repeat.
Switching to ng-repeat seems to resolve the issue.

Would mind posting a issue for this on github and provide a codepen example

Thanks for looking into it.

Created the issue on github here -

here is the pen -
