Opengl ES: drawing text

I'm trying (and trying and trying) to draw some text on screen using the Texture2D class. The result I have is just a green square on screen, with no text displayed. Googling around I found other guys with the same problem, but no response on how the solved it.
Can someone help please ?

Here is my drawView:

Texture2D* _textures[1];
    _textures[0] = [[Texture2D alloc] initWithString:@"0123456789" dimensions:CGSizeMake(1,1) alignment:UITextAlignmentLeft fontName:@"Arial" fontSize:12];
    //Set up OpenGL projection matrix
    //Initialize OpenGL states
    //glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA);
    glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer);
    glViewport(0, 0, backingWidth, backingHeight);
    glClearColor(0.0f, 0.0f, 1.0f, 1.0f);
        glOrthof(-1.0f, 1.0f, -1.5f, 1.5f, -10.0f, 10.0f);
    glTranslatef(0, 0, -9);
    glColor4f(0.0f,1.0f,0.0f,1.0f);//Change the object color to green
    glBindTexture(GL_TEXTURE_2D, [_textures[0] name]);

    [_textures[0] drawAtPoint:CGPointMake(0, 0)];
    //glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA);
    glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer);
    [context presentRenderbuffer:GL_RENDERBUFFER_OES];
