Did you set the Kinematics to “Follow Curve” when you created the bones from the curve? Normally, if you move the points on the curve, the bones would automatically follow the direction of the curve. If not, here's what you can do:

1) From the Character shelf, click on the Bones tool.

2) Above the viewport, you will see an option for your Kinematics setting, with a pull-down menu beside it. Choose “Follow Curve” from the pull-down menu.

3) Right-click anywhere in the viewport and from the pop-up menu, choose “Add Kinematics…”

4) Click on the first bone in your chain and hit Enter.

5) Click on the last bone in your chain and hit Enter.

6) Click on the curve you created to make the bones, and hit Enter.

By this point, if you move the points on the curve, the bones should deform to the curve. I hope this helps.
