Checked multiple checkbox using c# in Sharepoint 2013

Question

I have a problem! :( I programming in C# for Visual Studio 2012 and I am building an intranet that uses data from Sharepoint 2013. I have a problem in the register.

In SharePoint 2013, I have a list. In that list, one of the columns is of type "choice". When from C# I do calls to save the information, apparently is saved. But then, after seeing the results in Sharepoint 2013 I see is not so the information is not saved.

In SharePoint 2013 only save a default checkbox element (first element) but no save the correct selection.

My code:

---

SharePointConnector.SharePointEntities.TestDeInteresItem test = new SharePointConnector.SharePointEntities.TestDeInteresItem();

List<SharePointConnector.SharePointEntities.TestDeInteresInteresesPersonalesValue> personalList = new List<SharePointConnector.SharePointEntities.TestDeInteresInteresesPersonalesValue>();//0

test.AlumnoId = student.Identificador;
string[] auxPersonal = possibleInterest.Personal.Split(',');
for (int i = 0; i < auxPersonal.Length; i++)
{
        string s = auxPersonal[i];
        if (s.Length > 0)
        {
               var allInterest = englishDataContext.TestDeInteresInteresesPersonales.ToList();
               var element = allInterest.Where(x => x.Value.Equals(s)).FirstOrDefault();
               if (element != null)
               {
                            SharePointConnector.SharePointEntities.TestDeInteresInteresesPersonalesValue personal = new SharePointConnector.SharePointEntities.TestDeInteresInteresesPersonalesValue();
                            personal.Value = element.Value;
                            test.InteresesPersonales.Add(personal); //1
               }
        }
}

englishDataContext.AddToTestDeInteres(test); //2
englishDataContext.SaveChanges(); //3

--- //0 -> Initially, the list of elements (column when to type is election) is empty.

//1 -> The element is added successfully

//2 -> In this step, the information to added is correctly...

//3 -> ...but save allinformation correctly less the item cited (column when to type is election). This element is save default election (First element to checkbox)

Any ideas?

I've already solved the problem. The context was wrong.
