Description

Describe the problem

When adding shiny input elements (such as textInput()) via update_popover(), they are non-functional. In the following example, the initial textInput() created as part of the popover() call is fine, but as soon as this is replaced via update_popover(), it no longer works. The initial input element has a shiny-bound-input class, but the updated variant does not.

library(shiny)
library(bslib)

ui <- page_fixed(
  card(
    class = "mt-5",
    card_header(
      popover(
        "Dynamic popup",
        textInput("test", "test", "Initial"),
        id = "pop"
      )
    ),
    uiOutput("res")
  ),
  actionButton("update_popover", "Update popover")
)

server <- function(input, output, session) {

  output$res <- renderText(input$test)

  observeEvent(input$update_popover, {
    update_popover("pop", textInput("test", "test", "Updated"))
  })
}

shinyApp(ui, server)

If this is expected behavior, maybe advise against such use in the documentation. I could not find anything hinting at such problems.

Research direction

Start with the update_popover() entry point and reproduce the issue using the Shiny example in the report. Trace why the replacement textInput() lacks the shiny-bound-input class, then verify that inputs added through update_popover() remain functional and continue updating output$res.
