Answer 1

I think you may be missing some quotes around your data parameters and the framework cannot deserialize the json object correctly (ie. to the types on your signature):

data: '{catId: "' + ID + '",catFlag:"' + flag + '",catName: "' + catname + '"}',

(you just really need them around the string parameter catname…)

also, it may be that you pasted just part of your code, but you’re missing closing brackets at the and (2)
