title: How to monitor element changes on a UL element in Javascript
body: <p>I want to monitor a UL element for the changes in child elements such as li added or removed etc. The UL is used to display tabs in the screen where each li will be a separate tab. I don't have control to modify the tab script to call my own functions in my script file when the tabs are changed.</p>
  
  <p>I have to support IE browser mainly for this and have to do it using pure JavaScript.</p>
