Let's get into the problem. In datatable.js, to display the columns I define as follows:

    "aoColumns": [
                { "mDataProp": "IdProcesso", "sTitle": "Numero" }
                 ]

If you need to perform some function:

                 {
                    "mDataProp": "DataAbertura", "sTitle": "Data Abertura",
                    "fnRender": function (oObj) {
                        return //minha function vem aqui!
                    }
                },

Now comes the question, is it possible for me to add this function to the Json object dynamically? When I say dynamic I mean the fact that this object will be created by another function and at the end it returns me a string generated by JSON.stringify and the function gets unusable. I hope I have been able to explain my doubt.

How do you have at most one selected leader in all selects? A link to go back one level in the folder hierarchy and go to the level below in another folder

There is an alternative, using the function eval

The function eval executes the string passed to it, as you can see in the example below:

link

eval('alert("teste")');

This will cause the alert to appear on the screen. So my suggestion is that you save your function in string format, and execute it accordingly.
