var issue inside 'each'

I've this code

``` jade
ul
  each row in list
    li
      a(href='/path/#{app.type}/#{row.id}')= row.name
```

And the output its

``` html
<ul>
  <li>
    <a href='/path/5545629529/5545629529'>Row name</a>
  </li>
</ul>
```

The thing its that no matter how i call my first var inside the url, it takes the last value and replace both values with the last one.

Regards
