Using {{something}} in id

[Ulrar]

{{#each lasts}}
label(for='id_{{id}}') {{pseudo}}
p#id{{_id}} {{text}}
{{/each}}

That doesn't produce errors, the label is correct but the id of p is id_ and it contains the id and the text. The expected behavior would be to generate a p id="id_some_complicated_mongo_id" no ?
