Elasticsearch range query ( PHP Client )

I have this search query :

 $params = [
    'index' => 'veenendaal2',
    'type' => 'passanten2',
    'size' => $size,
    'body' => [
      'query' => [
        "match_all" => [],
        'filter' => [
          'range' => [
            'Tijdsperiode' => [
              'gte' => '2016-01-30 01:00:00',
              'lte' => '2016-01-30 08:00:00'
            ]
          ]
        ]
      ],
      'mappings' => [
        '_default_' => [
          'properties' => [
            'Tijdsperiode' => [
              'type' => 'date',
              'format' => 'yyyy-MM-dd HH:mm:ss'
            ]
          ]
        ]
      ]
    ]
  ];

But i can't get it to filter results between the 2 dates?

Any ideas how to fix this? DO i need to change the syntax?
