Remote validation isn't working in mvc. - asp.net-mvc

Question

I am using remote validator but it's not working even debugger isn't tracing that method.
public JsonResult CheckStrategyName(string StrategyName)
{
var ab = from a in db.Sterategy where a.StrategyName == StrategyName select a.StrategyName;
return !ab.Any() ? Json(true, JsonRequestBehavior.AllowGet) : Json(string.Format("Name Already esists"), JsonRequestBehavior.AllowGet);
}
I have used it here
[Required]
[Remote("CheckStrategyName", "St", ErrorMessage = "Already exists ")]
[Display(Name = "Name")]
public string StrategyName { get; set; }
Webconfig
<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
Where am I making mistake ? :(

Your server code & settings seems to be fine. Make sure the following are in place
You are using the TextBoxFor helper method to generate the relevant input field markup and it is inside a form.
#using (Html.BeginForm())
{
#Html.TextBoxFor(s => s.StrategyName)
#Html.ValidationMessageFor(s => s.StrategyName)
<input type="submit" value="Submit" />
}
You have included the javascript libraries needed for validation.
<script src="~/Scripts/jquery.js"></script>
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
