if test json against jsonlint see problem lies. best way handle this? think way i'm serializing c# model json not proper? use:

var jsonmodel = jsonconvert.serializeobject(model); 

any appreciated.

edit

issue fixed. problem serialization.

i fixed using method httputility.javascriptstringencode

var jsonviewmodel = httputility.javascriptstringencode(json.encode(model)); 

this solved problem. had pass knockout @html.raw(jsonviewmodel)

best regards , everyone!
