jQuery Grid Plugin - jqGrid

I want different ajax options to be applied to GET and POST requests from a jqgrid. 

Can ajaxGridOptions be used to do this?

example:

jQuery(”#tester”).jqGrid({

....FOR POSTing

    ajaxGridOptions : {type: 'POST',
                   success: function() {
                        alert(”Post Options!”);
                    }
            },

...FOR GETting

  ajaxGridOptions : {type: 'GET',
                   success: function() {
                        alert(”Get Options ”);
                    }
            },
