populate table in django template using knockout.js

This is the first time I am trying my hands on Knockout javascript. I am very naive to it so excuse me for the question.

I have a view which gives a json response.

views.py

    def get(self, request, code, format=None):
        data = self.get_details(code)
        paginator = Paginator(data, self.paginate_by)
        page = request.GET.get('page', 1)
        context = {}
        try:
            data_sent = paginator.page(page)
        except PageNotAnInteger:
        # If page is not an integer, deliver first page.
            data_sent = paginator.page(1)
        except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
            data_sent = paginator.page(paginator.num_pages)
        context['data'] = self.get_user(chain_code)        
        context['page_object'] = data_sent.object_list
        context['code'] = code
        data = json.dumps(context, cls=DjangoJSONEncoder)
        return HttpResponse(data)

I want to use this response to populate context['data'] in a table in my django template something like this:

Id  Name  Status

1   xyz    1
2   abc    2

datalist.html

    <script src="{% static "jsscript/datalist.js" %} "></script>

        <div class = "container">
           <div class = "page-header">


 <!---all headers data --->
       </div>
       <div class="tab-content">
           <table class="table table-bordered listingtable" >
                <thead>
                    <tr>
                      <th style="width: 10%;">Id</th>
                      <th style="width: 10%;">Name</th>
                      <th style="width: 20%;">Status</th>
                    </tr>
                  </thead>    

              <tbody>
               <!----script to populate table--->

             </tbody>
        </table>

I have gone through the official tutorial of knockout.js, but I'm not sure how to access the response from my API and populate the table in the template.

What I have tried so far:

datalist.js

var ViewModel = function(data) {
  var self = this;
    self.Id = ko.observable(data.id);
    self.Name = ko.observable(data.name);
    self.status = ko.observable(data.status);
};

ko.applyBindings(new ViewModel(data)); 

I know this solution is completely wrong but I'm just not sure how to proceed in the right path, Can someone just enlighten me about it?

Below is showing how to populate your data as table in knockout when you get your data from the server (you may use Ajax).

Example:https://jsfiddle.net/kyr6w2x3/108/

HTML:

   <table class="table table-bordered listingtable" >
     <thead>
       <tr>
         <th >Id</th>
         <th>Name</th>
         <th>Status</th>
       </tr>
     </thead>    
     <tbody data-bind="foreach:YourArrayList">
       <tr>
         <td data-bind="text:Id"></td> 
         <td data-bind="text:Name"></td>
         <td data-bind="text:Status"></td>
       </tr>                  
     </tbody>
   </table>

JS:

var yourData = [{id:1,name:"AAA" ,status:"AAA-status" },{id:2,name:"BBB" ,status:"BBB-status" },{id:3,name:"CCC" ,status:"CCC-status" }];

var MainViewModel = function() {
    var self = this;
    self.YourArrayList= ko.observableArray();
    self.YourArrayList($.map(yourData, function (item) {
             return new StatusItemViewModel (item);
        }));
};
var StatusItemViewModel = function(data) {
    var self = this;
    self.Id = ko.observable(data.id);
    self.Name = ko.observable(data.name);
    self.Status = ko.observable(data.status);
};

ko.applyBindings(new MainViewModel ());
