Ember model Not Bind Dynamically using Link-to

I created an ember demo,A parent view and it's child this is the parent view

<h1>A list of Todo Tasks</h1>
<ul>

<li></li>

</ul>

and Its js login is import Ember from 'ember';

export default Ember.Route.extend({
    model (){
        return [{
            "id" : 1,
            "desc" : "Try use ember"
        },
        {
            "id" : 2,
            "desc" : "Add it to github"
        },
        ];

    }
});

but when i use the link-to and navigate the data didn't show unless i refresh the page This is the child view

<h2>The Details for <span style="color: green;"></span> is : </h2>

<p></p>

<ul>
 
    <li></li>
    
</ul>


 

and its js logic

import Ember from 'ember';

export default Ember.Route.extend({
    model(params){

        if(params.id == "1"){
            return {
                name : "Ember SetUp",
                steps : [{
                    id :1,
                    do : "Download Ember Cli"
            },
            {
                    id :2,
                    do : "Generate New Project"
            },
            {
                    id :3,
                    do : "Generate Pages&Routes"
            }
                ]
            };
        }
        else{
            return {
                error : true,
                name : "Not Found",
                message : "There is no task with this id"
            }
        }
    }
});

iam using ember 2.5 and this is part of the router

this.route('todos', function() {
    this.route('details',{path : "/:id"});
  });
