Using Angular route params inside a link

Within my HTML view file I have a link that looks like this:

url: 'http://localhost:3000/readings?limit=100&nodeID=0001'

This is part of an Ajax call that gets readings from my local database for nodeID = 0001.

In the corresponding .js controller file I have the following function:

.controller('ReadingsViewCtrl', function ($scope, $routeParams) 

  {

     $scope.model = {
        message: $routeParams.id}


  });

I can now address the ID as {{model.message}} within my HTML view file.

What I want to do is somehow embed the {{model.message}} into the URL above so that I can get readings for arbitrary nodes, i.e. have something like url: 'http://localhost:3000/readings?limit=100&nodeID={{model.message}}'

This way I can get readings for an arbitrary nodeID passed in as a parameter instead of just node 0001. How can I do this?

EDIT: As asked here is the rest of the function that contains the URL property, it is part of an Ajax call that gets data from my database.

$.ajax({

        url: 'http://localhost:3000/readings?limit=100&nodeID=0001',
        dataType: 'json',
        type: 'get',
        cache: true, 
        success: function(data){
            var jsonobject = [];

            $(data).each(function(index, value){

                var list = [];
                var m = moment(value.time, 'YYYY-MM-DDTHH:mm:ss.SSSZZ');
                var ts = moment(value.time).valueOf();
                console.log(ts);
                list[0] = ts;
                list[1] = value.litres;
                jsonobject.push(list);

            })

             $('#container').highcharts('StockChart', {


            rangeSelector : {
                selected : 1
            },

            title : {
                text : 'Water consumption in Litres/sec'
            },

            series : [{
                name : 'Litres per flush',
                data : jsonobject,
                tooltip: {
                    valueDecimals: 2
                }
            }]
        });

            console.log(jsonobject);
        }
    });
