Very simple trigger fails to work?

When tested, the Village remains in control of the original player once the health goes below 50. Why does this not work?

I believe since you aren't using an attacking event it wont register that the unit is attacked. Try changing the event to A Unit is Attacked. Then the condition unit is == your unit and life of attacked unit < 50. Then do your actions.

Attacking unit wont exit the event doesnt refer to a unit attacking.
Here this is how you would do it a small test map.
let me know if you still have questions.

Edit: I used a unit takes damage because this can work for more then just attacking you might be wanting attackers only though.

Here's a vJass script that should work for you. I can't test it because my World Editor is broken atm :/

scope OwnerSwap initializer init
    private function SwapOwner takes unit u, real hp, player p returns nothing
        local integer spawnType = GetUnitTypeId(u)
        local real x = GetUnitX(u)
        local real y = GetUnitY(u)
        local real f = GetUnitFacing(u)
        call RemoveUnit(u)
        call CreateUnit(p, spawnType, x, y, f)
        call SetUnitState(u, UNIT_STATE_LIFE, hp)
        set u = null
        set p = null
    endfunction
    private function ConditionRun takes nothing returns nothing
        local unit u = GetTriggerUnit()
        local real hp = GetUnitState(u, UNIT_STATE_LIFE)
        local player p = GetOwningPlayer(GetAttacker())
        if GetUnitTypeId(u) == 'htow' and hp < 50. then
            call SwapOwner(u, hp, p)
        endif
        set u = null
        set p = null
    endfunction
    private function init takes nothing returns nothing
        local trigger t = CreateTrigger()
        local integer i = 0
        loop
            call TriggerRegisterPlayerUnitEvent(t, Player(i), EVENT_PLAYER_UNIT_ATTACKED, null)
            set i = i + 1
            exitwhen i > 11
        endloop
        call TriggerAddAction(t, function ConditionRun)
        set t = null
    endfunction
endscope

Use the event "A unit is attacked" in the conditions check if "Attack Unit = Village 0050 <gen>" and in the conditions check if "Healt of Village 0050 <gen>" is less than or equal to 50" Then you can use the action to change ownership of the unit to the attacking unit.
