Issues overriding templates

[joakDA]

Hi, I was able to override the overview template to adjunt the visual interface to my application, extending from my base template.

But I am not able to change the angular code in "_ngGrid.html.twig" and "translation.js" to an AJAX file to make request to the controller. Also, I don't want to include the references to Bootstrap 3 ( I am using Bootstrap 4.3), JQuery library (I am using JQuery 3.3.1) and Angular (I am not using it).

On the grid view, I want to use simple TWIG code on my template and have a simple JS file to make AJAX request to the controller. Also, I am using JQuery Datatable to improve table's functionality.

Please, could you provide a solution to change all the angular code to a JS file to get the translations data from the Symfony Controller? Thanks
