Describe the bug:
I'm noting that renderComplete seems to fire far too frequently for Discover saved searches. It seems to fire as each row is rendered, rather than when rendering completes.

Steps to reproduce:

1. Load a visualization that includes a Discover search
2. Load test code via the browser console:

$("doc-table.panel-content").on("renderComplete", function(){
console.log("renderComplete Ran: " + new Date().getTime() );
});

3. Use the tables paging buttons to force a refresh
4. Observe ~101 lines logged to the browser Console

Using an alert() in the test pauses things with each iteration that seems to show it occurring as each row is rendered

Expected behavior:
renderComplete would fire once when all table rows had completed rendering.
