change of input to clear text

[tanthiamhuat]

I have a button (input$savemodel_button), which when pressed, will write a text to SaveModel_text, as below:

savemodeltext <- eventReactive(input$savemodel_button, {
  blah blah...
  filename <- as.character(L5[2])
  savemodeltext <- paste0('Model saved to pickle file ',filename)
})
  
output$SaveModel_text <- renderText({
  savemodeltext <- savemodeltext()
})

Which the above serves the purpose I want. However, I need to implement anothet feature to clear that text when there is a change of input (input$change)

observeEvent(input$change, {
  ## need to clear SaveModel_text to blank where there is a change of input.
})  

Does observeEvent serves my purpose here? if yes, what is the needed code inside to clear the text?

Or should I use updateTextInput as below?
