created Field being updated when model is updated (saved)

[marksparrish]

I think the update function should not set the 'created' date and only set the 'update' date.

public function update(\Modler\Model $model)
    {
        $data = $model->toArray();
        $data['created'] = date('Y-m-d H:i:s');  // <- This should be removed
        $data['updated'] = date('Y-m-d H:i:s');

        list($columns, $bind) = $this->setup($data);
        $update = array();
        $properties = $model->getProperties();

        foreach ($bind as $column => $name) {
            $colName = $properties[$column]['column'];
            $update[] = $colName.' = '.$name;
        }

        $sql = 'update '.$model->getTableName().' set '.implode(',', $update).' where ID = '.$model->id;
        return $this->execute($sql, $data);
    }
