title: Can I let Shiny wait for a longer time for numericInput before updating?
body: <p>In my Shiny App, there are a few <code>numericInput</code> and <code>selectInput</code>. </p>
  
  <p>Shiny updates outputs during typing, especially when users type is slower in the numericInput.</p>
  
  <p><code>sumbitButton</code> could you be used to stop automatically updading. But I prefer to not to use it. </p>
  
  <p>How could I let Shiny waits for a longer time for <code>numericInput</code>?</p>
  
  <p>Thanks for any suggestion. Let me know if my question is not clear.</p>
