How do I get javascript to run when pdfjs is loaded?

Trying to auto-search with pdfjs, (and having hard time with the docs..)

THIS WORKS:

<input type="button" value="click-me" onclick="searchPDF('cpu');" />

THIS DOESN'T (jquery running ok)

 $(document).ready(function() {
    searchPDF('cpu');
 });

HOW DO SUSPEND EXECUTION UNTIL THE PDF IS PARSED? (OR WHY ISN'T IT WORKING)

MODIFIED viewer.html (thanks to PDF.js - Using search function on embedded PDF )

// search with PDF.js
function searchPDF(td_text) {
  //PDFView.findBar.open();
  $('#findInput').val(td_text);
  $("#tableDiv").focus();
  PDFView.findBar.findNextButton.click();

var event = document.createEvent('CustomEvent');

    event.initCustomEvent('find', true, true, {
        query: td_text,
        caseSensitive: $("#findMatchCase").prop('checked'),
        highlightAll: $("#findHighlightAll").prop('checked'),
        findPrevious: undefined
    });
    return event;

Finally found a solution for us that doesn't digest javascript for breakfast:

(thanks to

Based on viewer.html and added jquery:

$(document).ready(function() {
  document.addEventListener('textlayerrendered', function (e) {
    if (e.detail.pageNumber === PDFView.page) {
      // finished rendering, call a JS-function..
      searchPDF('cpu');
    }
  }, true);
});

function searchPDF(str) {
  alert('working');
