Push NotificatioN Android not work

ionic-v1
1

I have all the plugins, but installed the following code:

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
  alert("ffdfdfd");
 var pushNotification = window.plugins.pushNotification;
  pushNotification.register(
    successHandler,
    errorHandler,
    {
      'senderID':'912521945079',
      'ecb':'onNotificationGCM'
    }
  );
}

 function successHandler(result){
    console.log("RESULT "+result);
 }

 function errorHandler(error){
    console.log("ERROR "+error);
 }

 function onNotificationGCM(e){
    switch(e.event){
       case 'registered':
               if (e.regid.length > 0){
                  deviceRegistered(e.regid);
                  console.log("reg id "+e.regid);
                  alert("fff");
                  sessionServiceToken.set('token_device',e.regid);
               }
       break;

       case 'message':
           if (e.foreground){
              alert('Mensaje');
           }
       break;

       case 'error':
            console.log("ERROOOOR");
        break;

       default:
          alert("DEFAULT");
        break;
      }
    }

I do not receive any type of message or error, do not understand why it does not work.
