Proper way to execute a script tag in a Knockout H

问题:

I have the simple html page, where simple ul list defined with following viewmodel for it:

<div class="row">
  <div class="col-md-6">
    <button class="btn btn-link" data-bind="click: addItem">Add item</button>
    <ul data-bind="foreach: listItems">
      <li>
        <p data-bind="text: itemText"></p>
        <script>
          $(document)
            .ready(function() {
              console.log("new li has added");
            });
        </script>
      </li>
    </ul>
  </div>
  <div class="col-md-6">
    <pre data-bind="text: ko.toJSON($data, null, 2)"></pre>
  </div>
</div>
<script>
  function ItemViewModel(text) {
    var self = this;

    self.itemText = ko.observable(text || "");
  }
  function ListViewModel() {
    var self = this;

    self.listItems = ko.observableArray([]);
    self.addItem = function () {
      self.listItems.push(new ItemViewModel("new item: " + self.listItems().length));
    };
  }

  ko.applyBindings(new ListViewModel());
</script>

Adding items to list work perfectly, though script tag in list item template doesn't work. Each time when item adds to list, I need to execute all JavaScript code in corresponding script tag.

How to properly add items to Knockout's observable array with executing JavaScript code in them?
