Hi moon,
Little more information I would like to share regarding the issue
The para 7 in my notebook will render a bar chart. The scope.routeSelected
variable will be modified somewhere in the code. Now, I have modified the
code a bit so that the variable is incremented on selecting a bar from the
bar chart. This time, para 8 is run successfully. I suspect, the angular
watch works on some kind of mouse click?
regards
Bala
