Add button to list item in ionic and angular JS app

Hi I am trying to add a button in my ionic app to add a list item which has a dropdown options in it. So far I have:

HTML:

  <div class="list" ng-repeat="option in options">
<button class="button button-block button-positive" ng-click="addOption()">
    Add
  </button>
<label class="item item-input item-select">
    <div class="input-label">
      Name
    </div>
    <select>
      <option>Not interested</option>
      <option> Yes</option>
    </select>
    </div>

JS:

  $scope.option = $localStorage;

    $scope.addOption = function() {
    $scope.option.push();
  };

  $scope.closeOption = function(index) {
  $scope.alerts.splice(index, 1);
  };

I know the above must be wrong but I cant see where? I am fairly new to angular JS
