[Solved] Custom Command with server binding

[dani]

RESOLVED - Once removing Ajax needed to remove [HttpPost] from the Action.

1st Q. - I've added custom command to grid with server binding.
When I use Ajax(True) it works, but nothing happens to the grid.
I need to manually refresh the page to have it updated.
When I use Ajax(false)
I get a 404 error.

2nd Q. - I used cell action to hide the command when the status is canceled. This doesn't work as well.

Here is the grid code:

@(Html.Telerik().Grid(Model.myModel).Name("myModel")
.DataKeys(dk =>
    {
        dk.Add(g => g.DealID).RouteKey("DealID");
    })
        .PrefixUrlParameters(false)

        .Columns(c =>
            {
                c.Bound(o => o.DealID).Hidden(true);

                c.Bound(o => o.DealStatus.StatusName).Title("Status").ReadOnly();

                c.Bound(o => o.Remarks).Title("Remarks").ReadOnly();

                c.Command(p =>

                   p.Custom("cancelDeal")

                       // Set the text of the button
                    .Text("Cancel Deal")
                       // Specify which fields from the bound data item to include in the route (pass as action method arguments)
                    .DataRouteValues(route => route.Add(o => o.DealID).RouteKey("myDealID"))

                       // Make ajax requests
                    .Ajax(false)
                       // Which action method to call
                    .Action("CancelDeal", "MyController")).Title("Cancel");

            }).CellAction(cell =>
            {
                if ((cell.Column.Title == "Cancel") && (cell.DataItem.DealStatusID.Equals(SafeHedge.Shared.Enums.eDealStatus.DS_Closed) || cell.DataItem.DealStatusID.Equals(SafeHedge.Shared.Enums.eDealStatus.DS_Removed)))
                {
                    cell.HtmlAttributes["style"] = "visibility:hidden";
                }
            }))
