Trying to call node js REST api using loop sending only last call set of parameters

Question

In my application I am using AngularJS and nodeJS for rest api and its working fine. But when I try to call api using for loop its having some problems. Actually only last set of Parameters are passing to the api.

It means if I pass different parameters using loop 3 times then only last set of parameters passing to the api 3 times. First and Second are not send to api. Can anybody have any Idea??

Here is a sample code I use in Angularjs Factory.

var firstTimeData = {
                        "firstid": serializedJsonData.firstid,
                        "secondid": serializedJsonData.secondid,
                        "otherid": serializedJsonData.otherid

                    }
                    for (var i = 0; i < data[0].length; i++) {
                        for (var j = 0; j <= 2; j++) {
                            firstTimeData.dshdetailid = data[i][j].dshdetailid;
                            if ((data[i][j].defaultTitle).trim() == 'Scorecard Graph') {
                                BlankApi.getData(firstTimeData, 'slide' + j, 'periodname', 'amount');
                            }
                        }
                    }

To fix this issue you have to make asynchronous calls in loop,

Here in this code for loop get continuously executed without waiting for each api call to get finished.

check whether you are getting different parameters in each iteration through loop?
