MVC3 client validation not working -

i have required annotation on model:

[required(errormessage = "please choose option")] public bool? anydebts { get; set; } 

i have enabled client validation in web.config:

   <appsettings>     <add key="clientvalidationenabled" value="true" />     <add key="unobtrusivejavascriptenabled" value="true" />   </appsettings> 

i have referenced jquery scripts in layout:

<script src="@url.content("~/scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery-1.4.4.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery.validate.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery-ui-1.8.6.custom.min.js")" type="text/javascript"></script> 

what else need make client validation work? server side validation still working.

edit:

ah ha!

i have found client side validation working.

however, specifically, have found model properties not being validated client side annotated custom attributes. example:

[booleanrequiredtobetrue(errormessage = "you must agree statements listed")] public bool statementagree { get; set; } 

the code attribute:

public class booleanrequiredtobetrueattribute: requiredattribute {     public override bool isvalid(object value)     {         return value != null && (bool)value;     } } 

are these not validated client side anymore?

<script src="@url.content("~/scripts/jquery-1.4.4.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery.validate.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script> 

are required scripts client validation work.

and here's full working demo:

model:

public class myviewmodel {     [required(errormessage = "please choose option")]     public bool? anydebts { get; set; } } 

controller:

public class homecontroller : controller {     public actionresult index()     {         return view(new myviewmodel());     }      [httppost]     public actionresult index(myviewmodel model)     {         return view(model);     } } 

view:

@model appname.models.myviewmodel @{     viewbag.title = "home page"; } <script src="@url.content("~/scripts/jquery.validate.js")" type="text/javascript"></script> <script src="@url.content("~/scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script> @using (html.beginform()) {     <div>debts</div>     <span>yes</span> @html.radiobuttonfor(x => x.anydebts, true)     <span>no</span> @html.radiobuttonfor(x => x.anydebts, false)      @html.validationmessagefor(x => x.anydebts)     <input type="submit" value="ok" /> } 

remark: haven't included jquery-1.4.4.js in view because referenced in layout.
