I am learning knockout and trying out a small example below are the the three files that I have: index introduction introduction
I am using netbeans IDE for the development .

I am not getting the desired out put. The desired output is something like this in the below link
You are mixing self and this a lot in your code. I recommend cleaning that up first and see if things start working for you. Personally, I like to stay with self.xxxx format.
Also, remove the reference to "require" inside of your define block in the introduction.js file. That may be causing some issues. Either way, it's not needed.
Finally, it appears you are doing all of this using Oracle JET. Since the introduction.html is a view that will be used inside of ojModule, you do not need to have the < body> element defined a second time. The introduction.html is going to be a fragment that will take the place of the < div> that you have bound to ojModule.
