Bypas the url parmams methods

Hi team,

wher i read the doc about datatable i anderstand there is some features like server side filtering, sorting et paging need the parameter url like a get cat to https://myserver.com/page to sends parameters via get
like https://docs.webix.com/samples/server/packages_dynamic?start=50&count=40&continue=true

i use a custom url function like

theDataTableLoad = function () {
  webix.once(webix.extend($$(theDataTableLeft), webix.ProgressBar))

  console.log(arguments)

  $$(theDataTableLeft).disable()
  $$(theDataTableLeft).showProgress({
    type: "icon",
    hide: true
  });

  var input = webix.storage.session.get(theDataTableLeft);

  // console.log("input", input);

  webix
    .ajax()
    .post("/JSON/JSON/multi_slurp/getAllFromFilter/", JSON.stringify(input))
    .then(function (data) {
      var data = data.json().data;

      // console.log(data);
      $$(theDataTableLeft).clearAll();
      $$(theDataTableLeft).parse(data.data);
    });
};

so, do exists a tip or semething to gets the events + parameters please ?

i saw the beforeFilter and beforeSort event but pager is missing

          on: {
   			 onBeforePageChange: function () {
    		  console.log("onBeforePageChange", arguments);
