Mongoose+Node API delays db query

GET works great, DEL works great too. but POST... : What happens is that string goes in db. It does not show up(on my webapp). When I add a second string, it finally shows up. As if there is a delay?

 app.post('/api/todos', function(req, res) {
    todo.create({
        text : req.body.text,
        done : true
    }, function(err, todo) {
        if (err)
            res.send(err);
    });
        todo.find(function(err, todos){
    if(err)
        res.send(err)
    res.json(todos);
 });

But if I do it with delete, it works like normal. deleted the id and show the rest of the id's.

app.delete('/api/todos/:todo_id', function(req, res){
    todo.remove({
        _id : req.params.todo_id,
    }, function(err, todo){
        if(err)
            res.send(err);
});
    todo.find(function(err, todos){
        if(err)
                res.send(err)
        res.json(todos);
        });
});

I hope my question makes sense, I'm not so good at english
