i found way, mistake, syntax of validation mapping wrong.

there syntax :

var validationmapping = { 'name': {     create: function(options) {         return ko.observable(options.data).extend(         {           required:{                      params:true,                      message:"name required"                    }         });     } } } 

i updated fiddle.
