title: execute_script() doesn't work in python with selenium phantomjs
body: <pre><code>from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.common.exceptions import NoSuchElementException
  from selenium.webdriver.common.keys import Keys
  from bs4 import BeautifulSoup
  
  driver = webdriver.PhantomJS()
  #driver = webdriver.Firefox()
  driver.get('http://global.ahnlab.com/site/securitycenter/securityinsight/securityInsightList.do')
  driver.execute_script("getView('2218')")
  
  html_source = driver.page_source
  driver.quit()
  
  soup = BeautifulSoup(html_source)
  
  print(soup.h1.string)
  </code></pre>
  
  <p>When I use Firefox(), the result is [AhnLab Puts in Appearance at RSAConference for 4th Straight Year] that I want.
  But when I use PhanthomJS(), the result is [Security Insight] that I don't want.</p>
  
  <p>If I use PhantomJS(), I can't get the result that I want?
  I want to get the first result using a headless browser.</p>
  
  <p>thanks.</p>
