Multi-page site intro.js with Shiny

Question

I am trying to implement in.js multi-page functionality in a Shiny application.

Below is the code that does not work. The first tab works well, a popup for the second page is displayed, but without switching the tab.

ui.R

library(shiny)


    shinyUI(tagList(
            tags$head(
                    HTML("<link rel='stylesheet' type='text/css' href='css/introjs.min.css'>")
            ),
            navbarPage("Old Faithful Geyser Data",




      tabPanel(id = "fTab", "First tab",
            HTML("<h1 data-step='1' data-intro='This is a tooltip!'>Basic Usage</h1>"),
           sliderInput("bins",
                       "Number of bins:",
                       min = 1,
                       max = 50,
                       value = 30),

           plotOutput("distPlot"),
           HTML("<a id='startButton' class='btn btn-large btn-success' href='javascript:void(0);'>Help</a>")

      ),
      tabPanel(tabName = "sTab", "Second tab", id = "tt", 
               HTML("<h1 data-step='2' data-intro='This is a second tooltip!'>Basic Usage</h1>"),
                  sliderInput("bins2",
                              "Number of bins:",
                              min = 1,
                              max = 50,
                              value = 30),

                  plotOutput("distPlot2")
                  )
    ),
    HTML("<script type='text/javascript' src='js/intro.min.js'></script>"),
    HTML("<script type='text/javascript'>document.getElementById('startButton').onclick = function() {
         introJs().setOption('doneLabel', 'Next page').start().oncomplete(function() {
         window.location.hash = '#!tt?multipage=true';
         });
         };</script>")  
    ))

server.R

library(shiny)


    shinyServer(function(input, output) {

      output$distPlot <- renderPlot({

        x    <- faithful[, 2] 
        bins <- seq(min(x), max(x), length.out = input$bins + 1)


        hist(x, breaks = bins, col = 'darkgray', border = 'white')

      })
      output$distPlot2 <- renderPlot({


              x    <- faithful[, 2] 
              bins <- seq(min(x), max(x), length.out = input$bins2 + 1)


              hist(x, breaks = bins, col = 'darkgray', border = 'white')

      })

    })

The js and css files from intro.js are located in the js and css folders inside the www folder. Intro.js files can be found here

I assume that I am doing something wrong in a function in javascript code below ui.R. I tried to adapt the example from here by replacing window.location.href with window.location.hash and referring to the id of the tab, which is "tt".
