You need to listen for the ItemCommand event:

<telerik:GridButtonColumn UniqueName="Buy" ButtonType="LinkButton" 
    Text="Buy" ConfirmText="Add to cart?" 
    OnItemCommand="rg_ItemCommand" CommandName="AddToBasket" />

In your codebehind

protected void rg_ItemCommand(object sender, GridCommandEventArgs e)
{
    if(e.CommandName == "AddToBasket")
    {
        // Add to basket code here
    }
}

You may also need to set the CommandArgument during the ItemCreated or ItemDatabound events, or get it using something like rg.MasterTableView.DataKeyValues[e.Item.Index]["ItemId"].ToString(); after setting ClientDataKeyNames="ItemId" in your MasterTableView settings part in the ascx file (if it is databound).
