Node won't Populate JavaScript

I am working on a Node List that will populate as the user creates new tasks. I can not get the Node to populate its values, and it is keeping me from making any progress. Anything I look up for help does not give any help unless its Premade values in the code. Not sure why and trying to get help from my professor is like talking to a brick wall.
my JavaScript
function Node() {
this.task = document.getElementById('task').value;
this.priority = document.getElementById('priority');
this.owner = function () {
if (Math.random() > .5) {
return 'Bob';
} else {
return 'Joe';
}
};
this.next = null;
}
function SLinkedList() {
this.head = null;
this.append = function() {
var node = new Node();
var checkNode = this.head;
if (!checkNode) {
this.head = node;
return node;
} else {
var tail = this.findTail(this.head);
tail.next = node;
}
};
this.findTail = function (currentNode) {
if (currentNode.next === null) {
return currentNode;
} else {
return this.findTail(currentNode.next);
}
};
document.getElementById('item-output').innerHTML = "Item added. Task: " `+ Node.task + " Priority: " + Node.priority + "Owner: " + Node.owner;`
}
//unfinished to display all items because node won't populate
function displayItems() {
this.getTasks = function(node, tasks) {
}
}
var myList = new SLinkedList();
console.log(myList.head);

This is an assignment, but unforutnately this Professor has been very unhelpful all semester and even admitted that he hasn't touched much code since the early 90's. I think my University is screwing us over with uneducated teachers. Here is his requirements if it helps clear up any confusion.
While much of the code in JsBin Linked List (Links to an external site.)Links to an external site. can be reused, you will need to make a few modifications. These include:
- Create a new empty item list object with the SLinkedList function when the page initially loads.
- In the original code the Node object uses this.value. Replace it with this.task and this.priority and this.owner, etc so that it has the same attributes as an item object in the last assignment.
- In the original code when a new linked list object is created with the SLinkedList function it adds an initial node to this.head. In the new code this.head should be null.
- Modify the append method so when it appends, it checks to see whether the head node is null. If it is null append the new item to the head. Otherwise append to the end of the linked list.
- In the original function named displayitems() take out almost all of the code and have it call a new function named getTasks(node,tasks). This new function uses the same recursive approach used in gettail() (e.g. it calls itself) to walk through the nodes in the linked list. The function's first parameter is the head node of the linked list. The second parameter is an empty string. As the recursive function calls itself and traverses the linked list add to the tasks string with the task, priority and owner values in each node. After the traverse completes return the tasks string to displayItems(). displayItems() can then use the string to write the items (and appropriate html) to the DOM.
