Is double binding still a thing?

[OuTLaW66613]

So I've been trying to double bind a few things in my XML file to no avail.

I found a thread from a few years ago that had a script I thought should have worked but no dice:

this is the script I found:
<action name="v_strafe_vertical"> <rebind input="js3_y"/> <addbind input="js2_y"/> </action> <action name="v_strafe_lateral"> <rebind input="js3_x"/> <addbind input="js2_x"/> </action>

I had tried to double bind my afterburner so it would have looked something like this
<action name="v_afterburner">
<addbind input="js3_button1"/> <addbind input="js2_button1"/>
</action>

I haven't really messed around with code like ever but I do know that some shit needs to be in a proper order and case sensitivity is a serious thing... I've tried it in a few variations:
<action name="v_afterburner">
<addbind input="js3_button1"/><addbind input="js2_button1"/>
</action>

<action name="v_afterburner">
<addbind input="js3_button1"/>
<addbind input="js2_button1"/>
</action>

<action name="v_afterburner">
<addbind input="js3_button1"/>
<addbind input="js2_button1"/>
</action>

no dice... and something else weird happens when I try any of those (assuming trying to double bind anything)... the Afterburner gets switched to "button8"... default button?

pretty sure I just don't know what I'm doing but also thought this might not be doable anymore, figured you guys might know.
Any and all help is appreciated!
