Here is a very simple example of what you are trying to achieve based on your question:

simple.js

use(function () {
  var myproperty = properties.get("renderpagetype");
  return {callajaxvariable: myproperty};
});

simple.html

// simple.html
<script data-sly-use.simple="simple.js">

  /* assuming you use jquery */
  $.ajax({
    method: "POST",
    url: "/path/to/backend/servlet",
    someParam: "${simple.callajaxvariable @ context='scriptString'}"
  })
</script>
