Security :: Profile Is Not Saving In Aspnet_profile Table Besides Using Save Method?

I am using profiles it works fine but it is not saving in aspnet_profile table besides using save method

In Web Config:

<profile enabled="true" defaultProvider="SqlProvider">
<providers>
<clear />
<add name="SqlProvider"
type="System.Web.Profile.SqlProfileProvider"
connectionStringName="dd"
applicationName="AJAXEnabledFor Master Page"/>
</providers>
<properties>
<add name= "FirstName" />
<add name= "LastName" />
<add name= "Address1"/>
<add name= "Address2"/>
<add name= "City"/>
<add name= "State"/>
<add name= "Country"/>
<add name= "PinCode"/>
<add name= "Contact"/>
</properties>
</profile>

In Code Behind File

if (CreateUserWizard1.ActiveStep.Title == "Complete")
{
Roles.AddUserToRole(CreateUserWizard1.UserName, "Guest");
ProfileCommon p = (ProfileCommon)ProfileCommon.Create(CreateUserWizard1.UserName, true);
WizardStep Details = CreateUserWizard1.FindControl("Details") as WizardStep;
p.FirstName = ((TextBox)Details.FindControl("TextBox1")).Text;
p.LastName = ((TextBox)Details.FindControl("TextBox2")).Text;
p.Address1 = ((TextBox)Details.FindControl("TextBox3")).Text;
p.Address2 = ((TextBox)Details.FindControl("TextBox4")).Text;
p.City = ((TextBox)Details.FindControl("TextBox5")).Text;
p.State = ((TextBox)Details.FindControl("TextBox6")).Text;
p.Country = ((TextBox)Details.FindControl("TextBox7")).Text;
p.PinCode = ((TextBox)Details.FindControl("TextBox8")).Text;
p.Contact = ((TextBox)Details.FindControl("TextBox9")).Text;
p.Save();
}
