I would like to make the value `****here****`of the input `id="inputWorkload"` dynamic and related to the value of inputDuration (newTask.duration \* 2 )

How to do it with Vue js?

```html
<div class="col-sm-2">
    <div class="form-group">
        <label for="inputDuration">Duration (H)</label>
        <input class="form-control" id="inputDuration" min="4" step="4" type="number" v-model="newTask.duration">
    </div>
</div>
<div class="col-sm-2">
    <div class="form-group">
        <label for="inputWorkload">Workload</label>
        <input disabled class="form-control" id="inputWorkload" value="****here****">
    </div>
</div>

```
