Create a popup dialog box interactive

I was wondering if it is possible to create a popup dialog box interactive by using shiny (and shinyBS).

For example, I have a string and I want to change it and bef

You can do something like this using conditionalPanel, I would further suggest adding a button to ask for confirmation oppose to instant update.

rm(list = ls())
library(shiny)
library(shinyBS)

name <- "myname"

ui = fluidPage(
  uiOutput("curName"),
  br(),
  actionButton("BUTnew", "Change"),
  bsModal("modalnew", "Change name", "BUTnew", size = "small",
          textOutput("textnew"),
          radioButtons("change_name", "", choices = list("Yes" = 1, "No" = 2, "I dont know" = 3),selected = 2),
          conditionalPanel(condition = "input.change_name == '1'",textInput("new_name", "Enter New Name:", ""))    
    )
  )
)

server = function(input, output, session) {

  output$curName <- renderUI({textInput("my_name", "Current name: ", name)})

  observeEvent(input$BUTnew, {
    output$textnew <- renderText({paste0("Do you want to change the name?")})
  })

  observe({
    input$BUTnew
    if(input$change_name == '1'){
      if(input$new_name != ""){
        output$curName <- renderUI({textInput("my_name", "Current name: ", input$new_name)})
      }
      else{
        output$curName <- renderUI({textInput("my_name", "Current name: ", name)})
      }
    }
  })
}

runApp(list(ui = ui, server = server))
