Fill datatable in codeigniter by sending data

I have the following inconveniences: Sending data from the view with a data table passes it to the controller. The model resolves the query when it returns. The controller does not send the data in sight. I've seen everything on the web (it's easier to fill data without sending data), but nothing about sending data through the data. Please help … I attach pictures and code of the data table that is in the view, the control and the model. Thank you very much

// form image the data table is hidden until the data is sent

The image shows the date picker and a range field is hidden for its value to exist and be sent

// Show with the data table
