Failed to retrieve attributes in a Json response

[Nuo]

This is my first time using Kendo UI and I want to get a Json object from a Json file.

The Json string from Java controller looks like 
{"model": "Contract","rules": [{"initValues": ["5000"],"applyToFields" :["name","number"],"name": "MaxLengthRule"},{"name": "StartDateEndDateRule","applyToFields" :["startDate","endDate"]},{"name": "HierarchyValidationRule","applyToFields" :["hierarchy"]},{"name": "MasterContractValidationRule","applyToFields" :["hierarchy", "master"]},{"name": "JudgeDuplicatedRule","applyToFields" :["number"]},{"name": "ContractTypeRule","applyToFields" :["type"]}]}

And below is the script code. I want to get the rule attribute one by one. Now the alert with "Success!!!!!!!" is shown, 
 but I can only see some "undefined" in page after that. Could you help me on how to convert the Json string? Thanks a lot.

<script>
// document ready function
$(document).ready(function() {

var $validation = $("#validation");

// make an ajax call 
// to retrieve a JSON response 
$.ajax({
   // the url to the service
   url: "validation.do",
   contentType: "json",
   success: function(data) {
    alert("success!!!!!!!!!");
       $.each(data, function(index, item){
   $validation.append("<tr><td>" + item.model + "</td>" +
         "<td>" + item.rules + "</td></tr>");
       });
   }
});
});
</script>

Thanks
Best regards

Hello,

 Your code does not seem to include any of the Kendo UI widgets.
