I need your help because i can't callback the value from the function

look my example:

var data = askQuestion('Are you sure want to continue without adding a server', function(val){
return val; });

console.log(data);

function askQuestion(msg, callback){ $.confirm({

                      title: '',
                      content: msg,
                      type: 'dark',
                      theme: 'light',
                      animation: 'none',
                      animateFromElement: false,
                      columnClass: 'medium',
                      onContentReady: function () {
                          
                      },
                      buttons: {
                          ok: {
                              text: 'Συνέχεια',
                              btnClass: 'btn-dark float-right',
                              action: function(){
                                      
                                    callback(56);
                                    
                              }//end action
                          },//end ok
                          close: {
                                text: 'Ακύρωση',
                                 btnClass: 'btn-dark float-left',
                                 action: function(){
                                      
                                    callback(59);
                                    
                              }//end action
                          }
                        
                      }
                      
            });   

}
