Need to refresh a timer when player hits the ground. [Not working]

Hey guys, I am currently working on a project that requires a player's cooldown to be reset when they hit the ground. Currently I know I am doing it wrong and this glitch keeps happening because of it.




Here is the code that it uses.

Code:java

@EventHandler
    public void OnPlayerRocket(PlayerInteractEvent event){
        Player player = event.getPlayer();
        if (!plugin.Jiggly.contains(player.getName())){
            if(player.getExp() == 1f){   
                if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                    player.setVelocity(player.getLocation().getDirection()
                            .multiply(1.05).setY(.9));
                    player.setExp(0.50F);
                    plugin.RocketCooldown2.add(player.getName());
                }
            }
            else if(plugin.RocketCooldown2.contains(player.getName()) && player.getExp() == 0.5f){
                if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                    player.setVelocity(player.getLocation().getDirection()
                            .multiply(1.05).setY(.9));
                    player.setExp(0);
                }
            }
        }
            else if (plugin.Jiggly.contains(player.getName())){
                if(player.getExp() == 1f){
                    if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                        player.setVelocity(player.getLocation().getDirection()
                                .multiply(1.025).setY(.45));
                        player.setExp(.80F);
                    }
                }
                else if(player.getExp() == .80F){
                    if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                        player.setVelocity(player.getLocation().getDirection()
                                .multiply(1.025).setY(.45));
                        player.setExp(.60F);
                    }
                }
                else if(player.getExp() == .60F){
                    if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
 
                        player.setVelocity(player.getLocation().getDirection()
                                .multiply(1.025).setY(.45));
                        player.setExp(.40F);
                    }
                }
                else if(player.getExp() == .40F){
                    if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                        player.setVelocity(player.getLocation().getDirection()
                                .multiply(1.025).setY(.45));
                        player.setExp(.20F);
                    }
                }
                else if(player.getExp() == .20F){
                    if((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==Action.RIGHT_CLICK_BLOCK) && player.getItemInHand().getType() == Material.FIREWORK){
                        player.setVelocity(player.getLocation().getDirection()
                                .multiply(1.025).setY(.45));
                        player.setExp(0);
                }
            }
        }
 
    }
 
    int time;
    @EventHandler
    public void OnGround(PlayerMoveEvent e){
        final Player p = e.getPlayer();
        Bukkit.getServer().getScheduler().runTaskLater(plugin, new Runnable()
        {
            @Override
            public void run(){
                if(p.getLocation().add(0,-1,0).getBlock().getType() != Material.AIR){           
                    p.setExp(1);
                    plugin.Carrot2.remove(p.getName());
 
                }
            }
        }
