In your app you have to do just three things,\\ \\ 
1. Load the Script with
    app.LoadScript("DlgNewFile.js") 
2. Create a Button to call the Dialog and add it to the layout
    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
    btn.SetOnTouch(CreateNewFile);
    lay.AddChild( btn );
3. Write a function to call the Dialog
    function CreateNewFile()
    {
        // write the path where you want create the file 
        DlgNewFile = new NewFileDialog("/mnt/sdcard/");
        DlgNewFile.Show();    
    }
Or you can use this Example.
<code Javascript exampleapp.js>
//Called when application is started.
function OnStart()
{
    app.LoadScript("DlgNewFile.js")      
    lay = app.CreateLayout( "Linear", "VCenter,FillXY" );    
    btn = app.CreateButton( "Create a new File", 0.3, 0.1, "Alum" );
    btn.SetOnTouch(CreateNewFile);
    lay.AddChild( btn );
    app.AddLayout( lay );    
} 


//Create a new Dialog 
function CreateNewFile()
{
    // write the path where you want create the file
    DlgNewFile = new NewFileDialog("/mnt/sdcard/");
    DlgNewFile.Show();    
}
