Create CRUD Operations With My Kendo UI Data Grid & Symfony 3.0 Entites & Support Server Grouping, Server Filtering, Server Sorting & Server Aggregates

I'm a software developer working on a big project. I have the following kendo grid below. [login to view URL] I need this kendo grid to work with my PHP Symfony 3.0 Setup Server. I have made some progress so far, but am having a hard time figuring out grouping, filtering, sorting and aggregates (like count, sum) on grouping. I'm not sure what my JSON responses should be. Your job will be to create a route for one of my entities (company), a simple doctrine entity, and set it up so the 'Read', 'Update', 'Delete' and 'Create' work for it. I do NOT want to use the Kendo PHP Wrappers UNLESS it can sync nicely with my Doctrine Entities and Models. I prefer just something you write which will translate the commands coming from the Kendo Grid to the route to the correct JSON it needs. Then I will take a look at it and I'll need your help to answer any questions I may have regarding the technical details. Should be a very simple project if you understand the Kendo UI & how it works.
