Getting undefined data when i called a service

So I have a question that i've been trying to solve for hours.

My problem is that I'm getting the data faster than my services to load.

gen-service

function genEmpId() {
settingsService.getSettings().then(function (data) {
    var comId = data.data[0].companyId;
    console.log(comId);
    var test = comId + ' - ';
    return test;
});}

controller

function genId() {
   var data = genService.genEmpId();
   console.log(data); // getting the data too fast how to put a callback ?
}

So when my controller load its calling the service but im getting an undefined return value.

try this, In your code you not returning anything and another thing is it's async call to you have to wait until it finishes.

// gen-service

function genEmpId() {
  return settingsService.getSettings().then(function (data) {
    var comId = data.data[0].companyId;
    console.log(comId);
    var test = comId + ' - ';
    return test;
  });
}

// controller

function genId() {
  var data = genService.genEmpId().then(function (data) {
    console.log(data);
  })
}
