I want to modify the DOM of the newly rendered view by jquery and extending the kanbanRenderer. However, some field widget is always rendered after my jquery function ( I have already tried to override different function, such as start, _renderview and etc), I guess it is something related to async feature of the javascript.

I wonder if there is a function called when the view rendering is just finished. Such that jquery can select any element of the finally DOM you can see on the browser. Below is some code within the my extension of kanbanRenderer, it is just not working.

let myKanbanRenderer1 = KanbanRenderer.extend({
     start: function () {
         return this._super().always(function(){
             console.log($("span"))
         })
     }
 })
