filter object_list in django templete : I am new in Django and have some problem:
I create a template with object_list table and run in each object with loop:
but I also need to have filter by substring then when the user will filter the table will updates online.
I attch part from my code .. only the relvant
I debug the code and get the expected querset both in server print to log and in response ajax call but I still need to refresh point_list in some way or to determine the filters inside the templete and not in the server? 
Any help???
--------------------------------------------
1. I create view for this filter get the ajax request with substring value


def filters_points(request):

    point_list = Point.objects.all()

    try:

        req = request.GET.get("filterData")
        if req:
            point_list = Point.objects.filter(onsitePointName__icontains=req)

    except AttributeError:
        print("failed")

    #qs_json = serializers.serialize('json', point_list)
    #return HttpResponse(qs_json, content_type='application/json')

    return render_to_response('point/point_list_update.html', {'point_list': point_list})

2. in HTML templete:
 <input type="text" id="substring">
{% for point in point_list   %}
...
 <td> {{ point.mangoId }} </td>
 <td> {{ point.onsitePointName }}  </td>
....
