Child grid custom command button - kendo-ui

Question

I have a question based on my current situation, I have a grid with ClientDetail / Child grid inside of it. In my parent grid there is a custom command button, let say...
"columns.Command(
command => { command.Custom("Edit").Click("showEdit"); command.Destroy();
}).Width(160);"
and also i had my custom command button as well in my child grid, let say...
"columns.Command(
command => { command.Custom("Edit").Click("showSubEdit"); command.Destroy();
}).Width(160);"
Those 2 custom command should call different function which is "showEdit" & "showSubEdit". The problem is, every time custom command in child grid triggered, it always calls its parent's function which is "showEdit", however the child grid should call "showSubEdit".
Is there something i missed ?
NB :
function showEdit(e) {
...
}
function showSubEdit(e) {
...
}
Grid Code :

//columns.Template(t => { }).Title("No").ClientTemplate("#= renderNumber(data) #").Width(50);
columns.Bound(c => c._id).Visible(false);
columns.Bound(c => c.ActivityType.TypeTitle).Title("Type").Width(80);
columns.Bound(c => c.ActivityTitle).Title("Title").Width(120);
columns.Bound(c => c.DependenciesStr).Title("Dependencies").Width(120);
columns.Bound(c => c.ResourcesStr).Title("Resources").Width(120);

Answer 1

I got around the bubbling by checking if the element shown by the first command event is visible:
function showDetailsLevel(e) {
e.preventDefault();
originatingId = this.dataItem($(e.currentTarget).closest("tr")).Id
var wnd = $("#Details").data("kendoWindow");
if (!$("#Details").is(":visible")) {
wnd.center();
wnd.open();
var grid = $("#DetailGrid").data("kendoGrid");
grid.dataSource.read();
}
}
