Telerik MVC Grid : Ajax DataBinding posts additional parameter? - asp.net-mvc

Question

I've created a page which support editing multiple entities.
This page is called like: http://localhost/Personnel/EditMultiple?id=2944&id=7
On this page there is a GridView which should list these personnels in a grid.
This grid is defined like:
<% Html.Telerik().Grid<Web.Models.PersonnelMiniVM>()
.Columns(columns =>
{
columns.Bound(p => p.Name);
})
.DataBinding(d => d.Ajax().Select("_GetPersonnelByIds", "Personnel", new { personnelIds = string.Join(",", Model.PersonnelIds) }))
.Pageable(page => page.PageTo(Model.Page))
.Sortable(sorting => sorting.OrderBy(sortOrder => sortOrder.Add(p => p.Name)))
.Render();
%>
But when I look at the URL which is posted to the Personnel Controller, it's like:
http://localhost/Personnel/_GetPersonnelByIds/2944%2c7?personnelIds=7%2C2944&Personnel-size=5
What I don't understand is that why the 2944%2c7 is appended and this also gives me an 401 error when the URL gets too long.
The routing defined in Global.asax is like this:
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
How to solve this ?

See this :

Solution is to clear the id, like:
.DataBinding(d => d.Ajax().Select("_GetPersonnelByIds", "Personnel", new { id= "", personnelIds = string.Join(",", Model.PersonnelIds) }))
