MVC 4: Ambiguous request for action

I have the following code:

@using (Html.BeginForm("FolderChange", "EdiSender", FormMethod.Post, new {id = "ediFilesForm"}))
{
    var directoriesSelectList = new SelectList(Model.Directories);
    @Html.DropDownListFor(m => m.SelectedDirectory, directoriesSelectList, new {@Id = "Directories",     
    @style = "width:Auto;", @size = 20, onchange = "$('#ediFilesForm').submit()", name = "action:FolderChange"})

    var ediFilesSelectList = new SelectList(Model.EdiFileNames);
    @Html.DropDownListFor(m => m.SelectedEdiFile, ediFilesSelectList, new {@Id = "EdiFileNames",       
    @style = "width:Auto;", @size = 20})
}
<br/>

<form action="" method="post">
    <input type="submit" value="Send" name="action:Send" />
    <input type="submit" value="Delete" name="action:Delete" />
    <input type="submit" value="Refresh" name="action:Refresh" />
</form>

Here is a part of the controller:

    [HttpPost]
    [ActionName("FolderChange")]
    public ActionResult FolderChange(EdiFileModel ediFileModel)
    {
        ediFileModel = Load(ediFileModel.SelectedDirectory);
        return View("Index", ediFileModel);
    }
...

    [HttpPost]
    [MultipleButton(Name = "action", Argument = "Send")]
    public ActionResult Send(EdiFileModel ediFileModel)
    {
        ....
        return View("Index", ediFileModel);
    }

    [AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultipleButtonAttribute : ActionNameSelectorAttribute
{
    public string Name { get; set; }
    public string Argument { get; set; }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        var isValidName = false;
        var keyValue = string.Format("{0}:{1}", Name, Argument);
        var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);

        if (value != null)
        {
            controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
            isValidName = true;
        }

        return isValidName;
    }
}

When I press any of the buttons, I get the following message:

The current request for action 'FolderChange' on controller type 'EdiSenderController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Send(EdiSimulatorWebSender.Models.EdiFileModel) on type EdiSimulatorWebSender.Controllers.EdiSenderController System.Web.Mvc.ActionResult FolderChange(EdiSimulatorWebSender.Models.EdiFileModel) on type EdiSimulatorWebSender.Controllers.EdiSenderController

Could you please help me understand what is wrong with my view?

Thanks.

make sure on your controller you add the post attribute to your post method

public ActionResult FolderChange ... for the get

[HttpPost]
public ActionResult FolderChange... for the post
