I have gone through various links on google and found out that ngGrid does not support on focus editable functionality in 2.0
I created a customed control for this which can be make shift arrangement for on focus editable grid.
You all can check this on my blog :

Feedback is appreciated, this is not actual grid but a make shift arrangement that can be done.
