Return ID - Function

hmm so i tried like these (use a function) but wont work too. There are any possiblily to do this?

$('.content').on('click', function() {
  //console.log(data[1].id + " - " + data[1].live + " - " + data[1].name);

  console.log(live("summonersinnlive"));
});

function live(Name) {
  var clientID_ = "XYZ";
  var channelID = 0;

  $.ajax({
    method: "GET",
    url: "https://api.twitch.tv/kraken/users/" + Name + "?client_id=" + clientID_,
    success: function(data){
      handoff(data._id);
    }
  });

  function handoff(id)
  {
    channelID = id;
  }
  
  return channelID;
}
