Change the callback to pass this as well

<button class="reward_link_redeem_button_style" onclick="RedeemRPProduct(this, 'free_points_100')">click</button>

in the callback, the first argument (this, will be the button element)

function RedeemRPProduct (element, whatever) {
  element.className == "reward_link_redeem_button_style"
}
