title: Find or create with SequelizeJS
body: <p>I try to use the "findOrCreate" function of SequelizeJS but it doesn't work.</p>
  
  <p>The variable "created" is "undefined", so I don't know why because it's a variable used by SequelizeJS...</p>
  
  <pre><code>for( var i = 0; i &lt; tags.length; i++ ){
      global.db.Tag.findOrCreate({name: tags[i]}).success( function(tag, created){
          if( created ){
              global.db.PostTag.create({
                  PostId: id,
                  TagId: tag.id
              });
          }
      });
  }
  </code></pre>
