jQuery create HTML from JSON String

I have a JSON-Object which includes following example entry:

description":"<div>- diversen Diskutanten- Moderiert vom gro\u00dfartigen PreibischDebatte, Gesprochenes, Kontroverses<div class="btn-group"><a class"btn" href=""><i class="icon-map-marker"><\/i><\/a><a class"btn" href=""><i class="icon-map-marker"><\/i><\/a><\/div><\/div>"

Now i am trying to add this html to another element in my code with:

$('#desc_text').empty();
$('#desc_text').html(event.description);
$('#description').modal('show');

The problem is that the html is not parsed as html, which I thought jquery .html() would do. I also tried with append(), but no change too.

Does anyone know how to parse this as html?

EDIT 2: The whole workflow, because it seems little confusing:

first I do:

$events = json_encode($func->getAllDates());

the function does:

public function getAllDates() {
        $this->db->query('SELECT * FROM dates ORDER BY start');
        $result = $this->db->mysql_fetch_all();
        for($i = 0; $i < count($result); $i++) {
            $result[$i]['description'] = html_entity_decode(utf8_encode($result[$i]['description']));
        }
print_r($result);
        return $result;
    }

Output of $result in function:

[6] => Array
        (
            [id] => 17
            [title] => Sabotage Debatte: Politik im Keller
            [start] => 2012-11-29 00:00:00
            [end] => 2012-11-29 00:00:00
            [allDay] => 1
            [url] => 
            [description] => <div>- diversen Diskutanten- Moderiert vom großartigen PreibischDebatte, Gesprochenes, Kontroverses<div class="btn-group"><a class"btn" href=""><i class="icon-map-marker"></i></a><a class"btn" href=""><i class="icon-map-marker"></i></a></div></div>
        )

EDIT:

As in comments said: The quoting seems the answer, but I don't quote by myself and just use php-functions. Maybe the way I do is the wrong way.

I got something like this from my database:

<div>- diversen Diskutanten- Moderiert vom großartigen PreibischDebatte, Gesprochenes, Kontroverses<div class="btn-group"><a class"btn" href=""><i class="icon-map-marker"></i></a><a class"btn" href=""><i class="icon-map-marker"></i></a></div></div>

then I use

html_entity_decode(utf8_encode($result[$i]['description']));

to turn it back and then i use json_encode to put it in json-format. Shouldn't do any of this functions a correct quoting?

I hope you get to the workflow...
