[webkit-dev] how can I callback javascript function from webkit engine?

[rahulsundar]

Hi Alp Toker

I am involved in porting webkit. I was testing a .js file with some
callback. The file parsing is success and the script is executing fine. But
when I press some key the function in the .js file should be invoked. But it
wasnt working. Can u brief me, where exactly in Javascript to debug on this.
