I ran into this under the following circumstances:

• I was running Visual Studio 2013.
• My knockout project was using TypeScript 1.5.
• I was running my project in chrome using the Visual Studio debugger.
• I had poorly refactored some code and neglected to recompile or re-run the debugger.

Because of this, I believe what happened was I had bad TypeScript that wouldn't compile, only I wasn't getting any warnings or errors to that effect, and edits that I made to my TypeScript were not getting reflected properly in the auto-generated JavaScript files.

It might be uncommon that others will see this, but, I guess a word of warning is that you might run into this, or other unexpected behavior if you're editing TypeScript in place while running the VS debugger. I suspect that I had created the situation that Mark Robinson described in my auto-generated js files, but I did not see that in my TypeScript.
