How do I refresh SignalR connection if connection timeouts from inactivity

I have an angular application using SignalR. When the user is authenticated, I initialize a connection to the server. I believe that if client is inactive after a certain amount of time, it will disconnect. With the code below, how would I reconnect if it disconnects from inactivity?

var initializeSockets = function(){
  self.proxy = null;
  var connection = $.hubConnection(ENV.socketEndpoint,{
      qs: {token:User.getToken()},
      logging: false,
      useDefaultPath: false
  });
  self.proxy = connection.createHubProxy('messageCreatedEmitter');
  self.proxy.on('onMessageCreated',function(data){
    //the following is wrapped in a try catch
    //because it will break in a browser, and
    //will not allow the message to be emitted
    try {
      Alert.messageReceived();
    } catch (e) {
    }
    $rootScope.$emit('Messages:messageReceived',data);
  })

  if($.connection.hub && $.connection.hub.state === $.signalR.connectionState.disconnected
    || $.connection.hub.state === undefined){
    connection.start().done(function(){
      $log.info('connected');
    })
  }
}

 $rootScope.$on('User:userAuthenticated',function(event,user){
   initializeSockets();
 })

You could watch for the disconnect and reconnect;

$.connection.yourHubName.client.disconnect(function () {
    $.connection.hub.start();
});
