LineRenderer laser target not updating position

Greetings..

i have a 3d ship moving around in space from a top down view and asteroids that are also moving,

when i click on a asteroid with the mouse i want to turn on the laser and start draining the ore, if i click the same asteroid again or get out of range i want to turn off the laser,

mostly its working the laser comes out of my ship and updates its position as i orbit the asteroid,

but the problem is the end of the laser wont lock on to the asteroid, as the asteroid moves the end of the laser just stays where i first clicked.

please any help in the right direction on how to update the lasers target, thanks
