Starting with SignalR v0.5.1 it works this way:

$.connection.hub.stateChanged(function (change) {
    if (change.newState === $.signalR.connectionState.reconnecting) {
        console.log("liveFeed is reconnecting!");
    }
    else if (change.newState === $.signalR.connectionState.connected) {
        console.log("liveFeed is connected!");
    }
});
