You are creating the object in JSON format, which does not support variables such as attribute names.

I suggest creating the object and setting the field using the variable, like this:

var NomeCampo = $(this).attr('name');
var ValorCampo = $(this).val();
var payload = {};

payload[NomeCampo] = ValorCampo;

$.post(FormAction, payload,
    function(data){
        alert(data);
    }
);
