Try to replace these lines :
> column = Gtk::TreeViewColumn.new("Foo", renderer)
> column = Gtk::TreeViewColumn.new("Bar", renderer)
> column = Gtk::TreeViewColumn.new("Mix", renderer)

by these :
column = Gtk::TreeViewColumn.new("Foo", renderer, :text => 0)
column = Gtk::TreeViewColumn.new("Bar", renderer, :text => 1)
column = Gtk::TreeViewColumn.new("Mix", renderer, :text => 2)

This is the easy way to affect the content of a column to the data stored in 
the model. The last argument of the TreeViewColumn constructor is a hash of 
attributes which define a mapping between the data in the model, and what 
will appear in the TreeView (those attributes can be reaffected later with 
#add_attribute or #set_attributes)

In your case, you created this model :
> iter[0] = "First"
> iter[1] = "Second"
> iter[2] = "Third"

The attribute {:text => 0} means "I want to map directly the content of 
iter[0] to the rendered text of the "Foo" column".

Another way to do this is by using the #set_cell_data_func method, which let 
you define the rendering of the cell from the given block (using 
CellRenderer#text=, for example)
