2 databases but always take form the first in install

hi :) , I have 2 buttons ( install internal db & install remote db) ,

the problem is if i install the internal db first the the app will take it all the time even if install the remote db after , and also if i install the remote db first it will take it all the time even if i install the internal db after.

i have 2 diff db with same table but different numbers of rows on it ( i always delete the app from device and re-install to check )

my code : Install remote db button :

function takeRemoteDB()
{
    c = Titanium.Network.createHTTPClient();
    c.onload = function()
    {
        var filename ='Test1.sqlite';
        var appDir   = Titanium.Filesystem.applicationDataDirectory;
        var f = Titanium.Filesystem.getFile(appDir,filename);
            if (Titanium.Platform.name == 'android') 
            {
                f.write(this.responseData);
            }
    };
        c.open('GET','http://testtest.t15.org/Test1.sqlite');
        c.file = Titanium.Filesystem.getFile(appDir,'Test1.sqlite');
 
    c.send();
}

function InternalDB()
{
 
var db = Ti.Database.install('/Test1.sqlite', 'Test1'); 
var a = db.execute('SELECT title FROM archive');
 
 var counter=0
    while (a.isValidRow()) // just to test the contents of the db
    {
       if (counter=0)
       label1.text = a.fieldByName('title')+'\n';
 
       else{
       label1.text += a.fieldByName('title')+'\n';
    }   
 
    counter++;
    a.next();      
 
    }   
 
a.close();
db.close();
}

function contenOfRemoteDB ()
{
 
    var appDir = Titanium.Filesystem.applicationDataDirectory;
    var DBpath = appDir +'/Test1.sqlite';
 
 
    var db = Ti.Database.install(DBpath, 'Test1'); 
    var a = db.execute('SELECT title FROM archive');
 
 
 var counter=0
    while (a.isValidRow())
    {
       if (counter=0)
       label1.text=a.fieldByName('title')+'\n';
 
       else{
       label1.text+=a.fieldByName('title')+'\n';
        }
 
    counter++;
    a.next();      
 
    }   
 
a.close();
db.close();
 
}

my plan is to make internal db in the app and remote db for new contents ,

using Android 2.3 || ti build: 2.0.1.201204061639
