You can use the vertex group to achieve what you want. Take a look at the image.

Other option, could be to set the direction to apply the modifier, in this case to the Z axis, but it will replicate the effect on both faces (top and bottom) of the mesh.enter image description here

Part of the reason is a cube is connected to other vertices in 3D, unlike a 2D plane, and so calculates that way. So a plane would only stay within it's boundaries of y positioning (2D), whereas a 3D object is displaced in 3 dimensions.
