Bug onSelectRow in free-jqgrid - asp.net-mvc

Question

I use free-jqGrid v4.14.0. I have a table, when I click on a row in this table, I execute a stored procedure and in another table I enter the result.
The problem is that when you first click on a row in the table, the data does not load into the second table, and when the second button is clicked, the data appears, and this problem occurs only once, the following clicks immediately load the data into the second table.
When you first click in the browser console, you can see that the url stored procedure is loading: '# Url.Action ("GetAccident")',
$(document).ready(function () {
$("#jqg").jqGrid({
url: '#Url.Action("GetAccident")',
datatype: "json",
colNames: ['id_Accident', .......],
colModel: [
{ name: 'id_Accident', index: 'id_Accident', autowidth: true, sortable: false },
.....................
.....................
],
guiStyle: "bootstrap",
iconSet: "fontAwesome",
pager: "#pager",
rowList: [10, 20, 30],
rowNum: 10,
loadonce: false,
onSelectRow:
function (idRow) {
celValue = $('#jqg').jqGrid('getCell', idRow, 'id_Accident');
jQuery("#jqg1").jqGrid('setGridParam', { url: '#Url.Action("GetOrganizationCulpritByIdAccident")?celValue=' + celValue, page: 1 }).trigger('reloadGrid');
}
});
jQuery("#jqg1").jqGrid({
url: '#Url.Action("GetOrganizationCulpritByIdAccident")?celValue=' + 0,
datatype: "json",
colNames: ['id_Accident', 'Name Organization'],
colModel: [
{ name: 'id_Accident', index: 'id_Accident', autowidth: true, stype: 'text', sortable: true },
{ name: 'Name', index: 'Name', autowidth: true, sortable: true }
],
guiStyle: "bootstrap",
pager: "#pager1",
rowList: [10, 20, 30],
rowNum: 10,
});

I can't reproduce the problem. You can examine Network traffic of the demo https://jsfiddle.net/OlegKi/ed0yLkce/1/. I uses
datatype: "local"
in the second grid as initial option to prevent unneeded Ajax requests. I use additionally idPrefix with different values in both grids to be sure that one will have no conflicts with duplicates of ids. You will see in Network tab of Developer Tools that the request to for example https://fiddle.jshell.net/echo/json?celValue=test2 will be send it the second row is selected.
