I want to execute an event that would display something when

• a radio box is clicked
• someone types in the input text
• someone uses the select box
• or basically when something is done.

Automatically (without a button) it would change the output. I am not sure how to integrate keyup and keydown and onClick. Please help.

I tried this but it doesn't seem to work:

$(document).on('change','click','keyup',keydown', 'input','select', function() {

}
