Unable to run functions in sync mode NODEJS

I am using the async module to run list of functions in sequence but only the first function named getBaseLineList gets executed. The second one does not ? I want them to run one after the other.

NodeJS

function getBaseLineList(){
    var data=['a','b','c'];
    console.log("Inside getBaseLineList");
    return data;
}

function getBaseLineDetails(data){
    console.log("After we get the list"+data);
}

var data =[];
async.series([
    function(callback){    
        data = getBaseLineList();   
    },
    function(callback){
        getBaseLineDetails(data);
    }
]);

app.listen(port, host);
console.log('App started on port ' + port);
