title: Apollo GraphQL React - how to query on click?
body: <p>In the Apollo React docs <a href="http://dev.apollodata.com/react/queries.html#basics">http://dev.apollodata.com/react/queries.html#basics</a> there are examples of fetching automatically when the component is shown, but I'd like to run a query when a button is clicked. I see an example to "re"fetch a query when a button is clicked, but I don't want it to query initially. I see there is a way to call mutations, but how do you call queries?</p>
