how do I execute a function in angular.js, from an input checkbox?

I have a list of things with switches. How can I get each switch to call a function with that object and the switch as parameters?

I have tried to set the "ng-change" directive for my checkboxes, but the function doesn't seem to get called. How do I call the toggleSync function I made?

I am a total newb, so I'm sorry if I need serious help.

<div id="track-list" ng-controller="Controller" ng-init="update()">
  <div class="data-table">
  <table class="table table-hover tablesorter">
    <tr ng-repeat="item in items">
      <td><a href='{[{item.path}]}/{[{item.id}]}'>{[{item.title}]}</a></td>
      <td>{[{item.time_created}]}</td>
      <td>
        <div class=checkbox>
          <input ng-model="value" id="check{[{$index}]}" type="checkbox" ng-checked="!item.deleted" ng-change="toggleSync(item.id, this)" ng-true-value="YES" ng-false-value="NO"/>
          <label for="check{[{$index}]}">{{value}}</label>
        </div>
      </td>
    </tr>
  </table>


function Controller($scope) {
  console.log("init");
  $scope.items = [];

  $scope.toggleSync = function(objectId, input) {
    console.log("toggle sync");
  }
}
