| First: A chord is defined by at least three notes, e.g., C major includes the notes C, E, and G. So, the bassist is not generally playing chords, but rather notes which are [usually] IN the chord.
Second: Because you are not playing chords, you may play several different notes in succession over the same chord.
Third: When the chord changes, your note, depending on the note and the chord, may or may not change.
It's all about context. In your example of the notes G-C-A-C, the chords may actually follow your roots, i.e., the chords themselves may be G, C, A (or Am), and C, OR - you may be playing those notes over, say, an Am chord.
