Have you or anyone else solved this ?

Use jQuery to get the topics from the API.

<div id="mycats"></div>
<script>
$.getJSON('/api/category/1', function (data) {
  for (var i in data.topics) {
    $('#mycats').append('<div>' + data.topics[i].title + '</div>')
  }
})
</script>

@yariplus it would be better to make it in the server-side ?

It would, technically. You would have to make your own widget plugin to add the data to the widget template, or add a widget to widget-essentials. Using Categories.getCategoryTopics

psuedo example, check out widget-essentials for all needed code.

Plugin.renderMyTopicsWidget = function(widget, callback) {
  Categories.getCategoryTopics({
    cid: widget.req.params.cid || 1, // or whatever category ID you want.
    set: 'cid:' + widget.req.params.cid + ':tids',
    reverse: true,
    start: 0,
    stop: 10,
    uid: widget.uid
  }, function(err, result) {
    widget.data.topics = result

    app.render('widgets/yourwidget', widget.data, function(err, html) {
      translator.translate(html, function(translatedHTML) {
        callback(err, translatedHTML)
      })
    })
  })
}

widgets/yourwidget.tpl

<!-- BEGIN topics -->
<div>{topics.title}</div>
<!-- END topics -->
