Scrapy multiple requests and fill single item

I need to make 2 request to different urls and put that information to the same item. I have tried this method, but the result is written in different rows. The callbacks returns item. I have tried many methods but none seems to work.

def parse_companies(self, response):
    data = json.loads(response.body)
    if data:
        item = ThalamusItem()
        for company in data:
            comp_id = company["id"]

            url = self.request_details_URL + str(comp_id) + ".json"
            request = Request(url, callback=self.parse_company_details)
            request.meta['item'] = item
            yield request

            url2 = self.request_contacts + str(comp_id)
            yield Request(url2, callback=self.parse_company_contacts, meta={'item': item})
