xpath and scrapy in python 3.6 does not work

Question

I am trying to make this piece of code to work, so that I can scrapy some columns of a table from the website below: http://www.chiptiming.com.br/resultados/detalhes/2213609473

I have been trying to modify a lot of things in order to work, but no sucess, can anyone tell me what am I doing wrong? I put the log as well. Thanks in advance.

ps: I have read many posts similar to mine, but I couldn't find what is the reason, sorry if this post is kind of repeated.

from scrapy import Spider
from scrapy.selector import Selector

from stack.items import StackItem

class StackSpider(Spider):
    name = "stack"
    allowed_domains = ["chiptiming.com.br"]
    start_urls = 
         ['http://www.chiptiming.com.br/resultados/detalhes/2213609473',]

def parse(self, response):
    products = response.xpath('//*[@id="uptPnlResultGrid"]/div/table//tr')
    # ignore the table header row
    for product in products[1:]:
        item = StackItem()
        item['Coloc'] = product.xpath('td[1]//text()').extract_first()
        item['NumPeito'] = product.xpath('td[2]//text()').extract_first()
        item['Nome'] = product.xpath('td[3]//text()').extract_first()
        yield item

Answer 1

I tried your code and only got an empty products from this line:

products = response.xpath('//*[@id="uptPnlResultGrid"]/div/table//tr')

I think it's dynamic website, try splash.
