NodeJS - call a method after another method is fully executed

Calling a function with callback method
delete_chat_message(messageId,function(result){            
    if(result.success){
        console.log('Chat message is deleted successfully.');
    }else{
        console.log('Unable to delete Chat message.');
    }
});


Function Definition with callback execution
    delete_chat_message=function(messageId, calbackFunc){
    var results = {success: 0, id: messageId}
    
        /* Model to delete the chat message*/
        AjaxChatMessage.remove({id: messageId}, function(err, data) {
            console.log('here');
            if (err) {
                results.success = 0;
            }else{
                results.success = 1;
            }
            //call the callback function
            calbackFunc(results);
        }); 
    }
