p:selectOneRadio and h:selectOneRadio produces null values

I posted this question on the primefaces forum a couple of days ago but so far I have not got a solution. I have been trying to use OneRadio but I have been getting only null values from itemValue(s). This is a part of a large project so I extracted only relevant code and made a simple Dynamic Web Project (Eclipse Mars.1) with a view and a simple bean that test the case. The null values instead of itemValue appear regardless of using ajax or commandButton. I would appreciate your help in solving this puzzling phenomenon:

This is the view:

         content="text/html; charset=ISO-8859-1" />/>
   <title>Project</title>
   </ui:remove>
</h:head>
<body>
   <h:form>
      <p:layout style="width:190px; min-height:250px;">
       <p:layoutUnit position="center">
        <h:outputLabel for="strStatus" value="Project Status" />
        <p:selectOneRadio id="strStatus" value="testRadio.strStatus">
           <f:selectItem itemLabel="Active" itemValue="true" />
           <f:selectItem itemLabel="Inactive" itemValue="false" />
           <p:ajax event="click" listener="#{testRadio.onUpdate}" />
        </p:selectOneRadio>
        <p:commandButton style="width: 170px" value="Update Status"
           actionListener="#{testRadio.onUpdate}"/>
     </p:layoutUnit>
  </p:layout>
   </h:form>
</body>
</html>

This is the backing bean. One suggestion was not to use both @Named and @ManagedBean in the same class and I tried this correction but with no improvement.

package com.projectmanage.ui;
import javax.faces.bean.ManagedBean;
import javax.inject.Named;
import org.springframework.context.annotation.Scope;

   @Named
   @ManagedBean
   @Scope("session")
   public class TestRadio {

   private String strStatus;


   public String getStrStatus() {
     return strStatus;
   }

   public void setStrStatus(String strStatus) {
     this.strStatus = strStatus;
  }

   public void onUpdate(){
      String statUpdate = getStrStatus();
         System.out.println("Update Status: " +statUpdate);
      }
}

I am using Tomcat 8, Maven, and Spring and these are the configuration files:

Solution

Sorry for my mistake. I did not bind the radio button to a been property as pointed out by BalusC. I just omitted EL expression So, instead of:

<p:selectOneRadio id="strStatus" value="testRadio.strStatus">

the correct line is obviously:

<p:selectOneRadio id="strStatus" value="#{testRadio.strStatus}">

And it works.
