I used @KTW response mentioned on this Thread and here is the complete change
BundleConfig
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/modernizr-2.6.2.js",
"~/Scripts/jquery-2.2.3.js",

bundles.Add(new ScriptBundle("~/bundles/SignalRScripts").Include(
"~/Scripts/jquery.signalR-2.2.2.min.js",
"~/Scripts/signalRBundle.js",
"~/Scripts/Views/Search/SignalRFunctions.js"));
}
}
SignalRFunctions.js
$(function() {
// Declare a proxy to reference the hub.
var usersHub = $.connection.currentUsersHub;
//Create a function that the hub can call to broadcast messages.
usersHub.client.broadcastMessage = function(reservationNumber, usrName) {
//Message broadcast from server
//now find the id with reservationNumber on the page and to that append the user name
var id = '#' + reservationNumber;
if ($(id).length) {
if (usrName.length) {
itemsOpened($(id), usrName);
} else {
itemsClosed($(id));
}
}
//else {
// //is it possible that server broad casted for a reservationNumber and is not available at the client?
//}
};
//Accepts dictionary from hub and goes through search results
//https://stackguides.com/questions/7776337/reading-c-sharp-dictionary-in-javascript
usersHub.client.broadcastCollection = function (reservationNumberAndUsers) {
for (var resNumKey in reservationNumberAndUsers) {
if (reservationNumberAndUsers.hasOwnProperty(resNumKey)) {
//Message broadcast from server
//now find the id with ReservationNumber on the page and to that append the user name
var id = '#' + resNumKey;
if ($(id).length) {
if (reservationNumberAndUsers[resNumKey].length) {
itemsOpened($(id), reservationNumberAndUsers[resNumKey]);
} else {

}
}
}
}
};

if (typeof jsData !== 'undefined') {
if (jsData && jsData.length) {
for (var i = 0; i < jsData.length; i++) {
searchedReservationNumbers.push(jsData[i].UReservationNumber);
}
if (searcheduReservationNumbers.length !== 0) {
usersHub.server.getWorkingUsersOnUReservationNumber(searcheduReservationNumbers);
}
}
}
}).fail(function () { console.log('Could not Connect To SignalrHub!'); });
/*In case we would decide to continuously reconnect making connection to server.
$.connection.hub.disconnected(function() {
setTimeout(function() {

5000); // Restart connection after 5 seconds.
});*/
function itemsOpened(elem, id) {
var item = "Opened By - " + id;
elem.prop('title', item);
elem.css('background-color', 'chocolate');
};
function itemsClosed(elem) {
elem.prop('title', "");
elem.css('background-color', '');
};
});
signalRBundle.js
(function ($) {
$.ajax({
url: "/signalr/hubs",
dataType: "script",
async: false
});
}(jQuery));

SomePartialView.cshtml
Instead of writing below in above partial view
@using Localization
@using Newtonsoft.Json
@model NameSpace.ViewModels.FilterVM
@{
ViewBag.Title = Strings.Filter;
}
@using (Html.BeginForm())
{
<div class="large-12 columns">
---SOME CODE HERE
</div>
}
@section scripts
{
<script type="text/javascript" language="javascript">
var jsData = @Html.Raw(JsonConvert.SerializeObject(Model));
</script>
<script src="~/Scripts/jquery.signalR-2.2.2.min.js"></script>
<script src="~/signalr/hubs"></script>
<script src="~/Scripts/Views/Search/SignalRFunctions.js"></script>
}
This changed to
@using Localization
@using Newtonsoft.Json
@model NameSpace.ViewModels.FilterVM
@{
ViewBag.Title = Strings.Filter;
}
@using (Html.BeginForm())
{
<div class="large-12 columns">
---SOME CODE HERE
</div>
}
@section scripts
{
<script type="text/javascript" language="javascript">
var jsData = @Html.Raw(JsonConvert.SerializeObject(Model));
</script>
@Scripts.Render("~/bundles/SignalRScripts")
}
Notice
@Scripts.Render("~/bundles/SignalRScripts")
in partial view above.Without @KTW file above(ajax request to /signalr/hubs)
var usersHub = $.connection.currentUsersHub;
was always coming as null.
