joomla pagination shows same result on every page - joomla

Question

I have page of articles with more than 5 results. 5 results are displayed per page. Pagination shows up. When I go to different pages however, every page has the same 5 results.
My getItems():
function getItems()
{
$params = $this->getState()->get('params');
$limit = $this->getState('list.limit');
// 5
if ($this->_articles === null && $category = $this->getCategory()) {
$model = JModel::getInstance('Articles', 'ContentModel', array('ignore_request' => true));

$model->setState('filter.language', $this->getState('filter.language'));
$model->setState('list.ordering', $this->_buildContentOrderBy());
$model->setState('list.start', $this->getState('list.start'));
$model->setState('list.limit', $limit);
$model->setState('list.direction', $this->getState('list.direction'));
$model->setState('list.filter', $this->getState('list.filter'));

$model->setState('list.links', $this->getState('list.links'));
if ($limit >= 0) {
$this->_articles = $model->getItems();
if ($this->_articles === false) {
$this->setError($model->getError());

parent::display($tpl);
}
If i print the contents of $pagination in the view.html.php here:
$this->_prepareDocument();
echo '<pre>'; print_r($pagination); exit();
parent::display($tpl);
I get the following results:
In my template file I echo the pagination:
<?php echo $this->pagination->getPagesLinks(); ?>
By the way, clicking on 'next' does change the url into ...?start=5.

This line in populateState is commented out
$this->setState('list.start', JRequest::getVar('limitstart', 0, '', 'int'));
Uncomment it change it tot get the "start" parameter:
$this->setState('list.start', JRequest::getVar('start', 0, '', 'int'));
