backbone.js events not firing after re-render

[EDIT: I solved earlier problem by calling delegateEvents(), but shouldn't have to. Re-posting w/more info.]

I have a View that when rendered has a login button on it with a click event attached. First render all works: click on button and upon successful ajax call the login prompts disappear and welcome view (LoggedInView) is displayed. But, if I navigate back to this View later (#foo) the UI renders but the event association is gone without manually forcing the issue by calling delegateEents().

What happened that my events didn't re-associate themselves?

LoginView = Backbone.View.extend({
    template: _.template($("#loginTemplate").html()),
    initialize: function(stuff,router) {
        _.bindAll(this,'render','rc','gotProfile');
        this.model.bind("rc",this.rc)
        this.router = router;
    },
    events: {
        'click .loginButton': 'login'
    },  
    render: function() {
        $(this.el).html(this.template(this.model.toJSON()));
        $(this.el).find(".actionButton").button();  // Button
//      this.delegateEvents(this.events);  // NEEDED!  Re-wire events on re-render
        return this;
    },
    rc: function(code) {
        switch(code) {
            case errCodes.USER_NOT_FOUND:   this.notFound(); break;
            case errCodes.OK:               this.loginOk(); break;
            default:                            this.otherErr(); break;
        }
    },
    login: function() {
        clearErrors( $('[rel="req"]') );
        var okReq = validate( $('#login [rel="req"]'), validateReq );
        var okEmail = validate( [$('#uid')], validateEmail );
        if( okReq && okEmail ) {
            this.model.set({'uid':$('#uid').val().trim(),     'pwd':$('#pwd').val().trim()});
            this.model.fetch();
        }
    },
    notFound: function() {
        validate( [$('#uid'),$('#pwd')], function(){return[false,"Invalid user / password"]} );
    },
    otherErr: function() {
        vali
