Use a filter (custom filter) in v-html property

I have a filter that converts line breaks to html, in previous versions normally i use the filter like this:

{{ description | nl2br }}

That actually works but the html its escaped, so doesn't show as HTML, the triple mustach doesn't work {{{ description | nl2br }}} (seems that its deprecated)

so i found in the documentation the v-html="" that works with html string but when i apply the filter it doesn't work, i didnt found the syntax o how can achieve that:

<p v-html="description|nl2br"></p>
// this doesn't work returns: Property or method "nl2br" is not defined on the instance but referenced during render

Any idea?
