Save button not storing information within the sql database

I am new to C# guys so please be kind and any help is appreciated :).

My save button is not retaining the information that it should on the sql database and I'm slightly perplexed as to why?

This is my code below...

private void btnSave_Click(object sender, EventArgs e)
{
    try
    {
        InformationBindingSource.EndEdit();
        test.SaveChangesAsync();
        panel.Enabled = false;
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Message", MessageBoxButtons.OK, MessageBoxIcon.Error);
        InformationBindingSource.ResetBindings(false);
    }
}

What I don't understand is that on the sql server profiler it recognises the connection and the button also claims to store the information. Although, if a restart the project and start it back up, or look in sql, the information isn't there.

I have also declared the "entity.infrastructure" and I've just come to a stand still with no idea why it's not storing the information :(
