URL field not working with flexigrid no response from URL - json

Question

When I pass the URL I am getting a no response from the url otherwise if I specify the corresponding WCF service page which is included in my project it is working is it any cross domain issue what would be the possible issue
<form id="sform" runat="server">
<table id="flex2" style="display:none"></table>
<script type="text/javascript">
$(document).ready(function () {
var user_id = 1;
var data = { UserID: user_id };
$("#flex2").flexigrid({
useInlineEditor: true,
//singleSelect: true,
rowClick: function (row) {
//var r=this.DataSource.rows[row.rowIndex];
//var p=$(row).offset();
//alert(r[this.DataSource.key]+" "+r.Name+" offset:"+p.top+","+p.left);
//this.grid.inlineEditor.edit(row);
},
url: 'http://192.168.10.91:5001/Service.svc/GetStates',
method: 'POST',
dataType: 'json',
colModel: [
{ display: 'Hours', name: 'hours', width: 40, sortable: true, align: 'center' },
{ display: 'DOC', name: 'doc', width: 180, sortable: true, align: 'left' },
],
searchitems: [
{ display: 'Type', name: 'cmetype' }
],
onError: function (jqXHR, textStatus, errorThrown) {
alert("flexigrid failed " + errorThrown + jqXHR + textStatus);
},
sortname: "type",
sortorder: "asc",
usepager: true,
title: 'States',
useRp: true,
rp: 15,
showTableToggleBtn: true,
width: 800,
height: 200
});
});
//This function adds paramaters to the post of flexigrid. You can add a verification as well by return to false if you don't want flexigrid to submit
function addFormData() {
//passing a form object to serializeArray will get the valid data from all the objects, but, if the you pass a non-form object, you have to specify the input elements that the data will come from
var dt = $('#sform').serializeArray();
$("#flex2").flexOptions({ params: dt });
return true;
}
$('#sform').submit(function () {
$('#flex2').flexOptions({ newp: 1 }).flexReload();
return false;
});
</script>
</form>

Make sure that the svc service is accesibile and that it can accept post requests.
If all works well, check that the response is JSON and is valid.
