title: Missing html in response using python requests and beautifulsoup4
body: <p>When I view the page source in my browser, the html I am after appears there. However, when I make a requests using python requests the html doesn't appear.</p>
  
  <p>The url I'm trying to scrape is <a href="http://dota2lounge.com/match?m=13362" rel="nofollow">http://dota2lounge.com/match?m=13362</a>, and the specific html I am after in the page is.</p>
  
  <pre><code>&lt;div class="full"&gt;
      &lt;a class="button" onclick="ChoseEvent(13362,'Whole Match',false)"&gt;Match&lt;/a&gt;
      &lt;a class="button" onclick="ChoseEvent(13392,'1st Game','1462327200')"&gt;1st Game&lt;/a&gt;
      &lt;a class="button" onclick="ChoseEvent(13424,'2nd Game','1462327200')"&gt;2nd Game&lt;/a&gt;
      &lt;br&gt;&lt;div id="toma" class="full" style="background: #444;line-height: 2.5rem;border: 1px solid #333;text-align: center;"&gt;Whole Match&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I'd like to get the 'onclick' values of the buttons. So far I've tried:</p>
  
  <pre><code>r = requests.get('http://dota2lounge.com/match?m=13268')
  soup = bs(r.content, 'lxml')
  buttons = soup.find_all('a', class_='button')
  </code></pre>
  
  <p>Which doesn't work.</p>
  
  <pre><code>r.content
  </code></pre>
  
  <p>Doesn't appear to show the html either.</p>
