Problems with RadGrid Rebind after ItemCommand

[Malichone]

Currently I have a grid with multiple rows. The last column of the grid is an imagebutton inside a GridTemplateColumn to "remove" the row. What i mean by remove is actually change the value of another column in a GridBoundColumn and hide the desired row. 

I currently have an itemcommand and commandname on the imagebutton.

<asp:ImageButton runat="server" ID="imgRemoveCostCenter" ImageUrl="~/Images/Remove.png" OnItemCommand="rad_CostCenters_ItemCommand" CommandName="HideCostCenter" />

The grid itself has the OnItemCommand event bound.

<telerik:RadGrid ID="rad_CostCenters" OnItemCommand="rad_CostCenters_ItemCommand" AllowMultiRowEdit="true" AutoGenerateColumns="false" EnableTheming="true" Skin="Default" AllowSorting="false" runat="server" ShowHeader="true" OnItemDataBound="Rad_ManagersList_ItemDataBound">

Have a GridTemplateColumn to hold the "ActionID"

<telerik:GridBoundColumn UniqueName="ActionID" DataField="ActionID" Visible="false" />

and finally have the function in the code-behind:

protected void rad_CostCenters_ItemCommand(object sender, GridCommandEventArgs e)
{
    GridDataItem item = (GridDataItem)e.Item;

    int _ActionID = Convert.ToInt16(item["ActionID"].Text);

    if (e.CommandName == "HideCostCenter")
    {
        _ActionID = -1;
    }
    rad_CostCenters.Rebind();
}

protected void Rad_ManagersList_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        DataRowView drv = (DataRowView)e.Item.DataItem;

        int _ActionID = Convert.ToInt16(item["ActionID"].Text);

        if (_ActionID == -1)
        { item.Display = false; }
    }
}

How can I get this to set the actionID so it can be rebound?
