title: Getting input values without rerender
body: <p>I have a text input (for the search text) and a button (to initiate the search). It seems from all the examples, that in order to have the searchtext value available in my search click handler (to trigger an Action), I have to have the input use a state value and update the state when the onChange occurs. This causes rerendering. How can I avoid all the rerenders when the user is just typing chars into the input? I only want the value at the time the search button is pressed.</p>
