Why are li's not showing up with python requests response?

I have a homework project with web scraping and am suppose to collect all the even information for a month from a school website. I am using Python with Requests and Beautiful Soup. I have written some code to grab a url and am trying to grab all of the li's from the page that hold the event information. However, when I go to grab all of the li content I noticed that I am not receiving all of them. I have been thinking it is due to the style of "overflow:hidden" for the ul but why am I able to get the first few li's then?

from bs4 import BeautifulSoup
import requests

url = 'https://apps.iu.edu/ccl-prd/events/view?date=06012016&type=day&pubCalId=GRP1322'
r = requests.get(url)
bsObj =  BeautifulSoup(r.text,"html.parser")    

eventList = []
eventURLs = bsObj.find_all("a",href=True)
print len(eventURLs)

count = 1
for url in eventURLs:
    print str(count) + '. ' + url['href']
    count += 1

I am printing out the urls because I plan on going to the href link inside of the events to get the full descriptions and other metadata provided. However, I am not getting all of the event lis. I am only getting the first 5. The links in the output that I get that are for the events are numbers 19 to 23. The page has 10 total events though.

output:

TLDR: I am not getting all the links from the lis on a page when I use Python requests and beautiful soup. Why am I not getting the links and is there a better way of going about this problem?

Edited to give answer: The links I needed were all being created with Javascript and since Requests and Beautiful soup do not run the Javascript I have instead moved to Selenium with PhantomJS. However, an answer below shows how to get the information created by Javascript by using parameters in Python Requests which is a perfect way of doing this!
