Sadanandachar,

  Calling a restful service is quite simple using esriRequest:

    _showImprovements: function(index, item){
        var ppin = this.list.items[this.list.selectedIndex].ppin;
        this.shelter.show();
        var requestHandle = esriRequest({
          url: 'http://your server/your service/your function',
          content: {
            ppin: ppin,
            f: 'json'
          },
          handleAs: "json",
          timeout: 10000
        },{useProxy: true, usePost: false, disableIdentityLookup: true});

        requestHandle.then(lang.hitch(this, function(improvementsJSON, io){
          console.info(improvementsJSON);
          //do something with the retrned json here

        }), lang.hitch(this, function(err){
          this.shelter.hide();
          console.info(err);
        }));
      }
