I have the same problem:

does not work.

I tried but reload is triggered only after alert is shown ex:

$(“#gs_title”).val('test');

$('#mygrid').trigger('reloadGrid');

nothing.

$(“#gs_title”).val('test');

alert('loaded');

$('#mygrid').trigger('reloadGrid');

works. I can't figure why, but using $(“#mygrid”)[0].triggerToolbar() does not works too.
