My ideas doesn't show

I checked my code and it's very similar to Craig's code, i don't know why it doesn't show the list of ideas

get("/ideas",(req,res) -> { Map<String,Object> model = new HashMap<>(); model.put("idea",dao.findAll()); return new ModelAndView(model,"ideas.hbs"); }, new HandlebarsTemplateEngine());

post("/ideas",(req,res) ->{ String title = req.queryParams("title"); CourseIdea courseIdea = new CourseIdea(title,req.cookie("username")); dao.add(courseIdea); res.redirect("/ideas"); return null; });

{{#partial "content"}} <h1>Current ideas</h1>

<ul>
    {{#each ideas}}
        <li>{{ title }}</li>
    {{/each}}
</ul>

<form action="/ideas" method="post">
    <input type="text" placeholder="What's your idea?" name="title">
    <button>Suggest!</button>
</form>

{{/partial}} {{> base.hbs}}

Here is Craigs code chunk

        get("/ideas", (req, res) -> {
            Map<String, Object> model = new HashMap<>();
            //omiited code
            model.put("ideas", dao.findAll());
            // omitted code
            return new ModelAndView(model, "ideas.hbs");
        }, new HandlebarsTemplateEngine());

And here is yours

get("/ideas",(req,res) -> { 
  Map<String,Object> model = new HashMap<>(); 
  model.put("idea",dao.findAll()); 
  return new ModelAndView(model,"ideas.hbs"); 
}, new HandlebarsTemplateEngine());

Do you see the difference?
