These are leaves not cuttings.
Week may not be enough for roots, or they are not healthy enough to grow roots. Just leave them alone and wait little longer.
Even if healthy, don't expect that all leaves will root.
Most leaves in your photo look like they are damaged where the roots are supposed to grow - I circled them (that's what I see in the photo) and I don't think they will root:
