CanJs - Iterate through an array in mustache and create observables

    ...    


option:{
  array: new can.List([1, 2, 3, 4, 5])
}
    ...

{{#each option.array}}
  <div>
    <label for="d{{@index}}"></label>
    <input id="d{{@index}}" can-value="option.array[{{@index}}]"/>
  </div>
{{/each}}

Above code generates 5 text boxes with correct id. But it does not create observables.

What is the correct format that I should provide to can-value attribute to make it an observable?
