SignalR and .NET - asp.net

Question

I'm basically trying to dynamically create a list element and update it across multiple clients. I'm using SignalR library of .NET. Following is my code.
$(function () {
// Reference the auto-generated proxy for the hub.
var listSync = $.connection.myHub1;
console.log("List Sync ");
// Create a function that the hub can call back to display messages and toggle.
listSync.client.addNewItemToPage = function (name, url) {
console.log("List Sync 3");
var play_list = document.getElementById('playlist');
var empty = document.getElementById('empty');
if (empty != null) {
empty.remove();
}
var pli = document.createElement("li");
var ptag = document.createElement('a');
var icon = document.createElement('i');
icon.setAttribute('class', "fa fa-toggle-right");
ptag.setAttribute('href', "#");
ptag.setAttribute('class', "play_track");
ptag.appendChild(icon);
ptag.innerHTML += name;
ptag.type = url;
pli.appendChild(ptag);
play_list.appendChild(pli);
//handler to play songs by playlist
var favLinks = document.getElementsByClassName('play_track');
for (var j = 0; j < favLinks.length; j++) {
var favLink = favLinks[j];
favLink.onclick = function (e) {
e.preventDefault();
xurl = this.type;
myFunc();
}
}
};
// Start the connection.
$.connection.hub.start().done(function () {
window.listFunc = function listFunc(name, url) {
console.log("List Sync 1");
// Call the Send method on the hub.
listSync.server.update_playlist(name, url);
console.log("List Sync 2");
}
});
});
The problem is it doesn't go into the function listSync.client.addNewItemToPage. Can someone please tell me why?
