jQuery Grid Plugin - jqGrid

I have some grid. I use editing. In editing I call new grid :

function fioelem (value, options) {
  var el = document.createElement("input");

...

$(el).dblclick( function () {
    var pos = $("#editmodsotrudnik").position();
    if (pos == null) pos=$("#editmodcontra").position();
    else if (pos.left == 0) pos =$("#editmodcontra").position();
    var fd = $("#fld").html();
    if (fd.length==0) $.get("fizlico_table.php","",function(data){
        $("#fld").html(data);
        $("#fiz_dialog").dialog("option","position",[pos.left,pos.top]);
        $("#fiz_dialog").dialog("open");
        },"text");
    else {
        $("#fiz_dialog").dialog("option","position",[pos.left,pos.top]);
        $("#fiz_dialog").dialog("open");
    }
  });

...

}

In this new grid I use edding and adding too. Than when I back in first grid, I haven't ending editing because I have editing properties from second grid. What can I do?
