Trying to Eliminate Players in a Tournament via button - node.js

Question

I am trying to implement the update route into a poker site I am building. I have been able to get the players to appear on the show page but I would like to update the mongo DB from inTournament: "Yes" to inTournament: "No" when the Eliminate button is selected for that player. I have included my code below. Thank you, in advance, for any help with this.
======================= app.js UPDATE ROUTE=======================
app.get("/seating", function(req, res){
//Get all players from poker_DB
Seat.find({inTournament: "Yes"}, function(err, allseats){
if(err){
console.log(err);
} else {
shuffle(allseats);
res.render("seating", {seats: allseats});
}
});
});
//Update player's tournament status
app.put("/seating", function(req, res){
Seat.findByIdAndUpdate(req.params.id, req.params.inTournament, function(err, updatedStatus){
if(err) {
console.log(err);
} else {
res.send("Data Updated");
}
});
});
======================= SHOW PAGE=======================
<div class ="row text-left" style="display:flex; flex-wrap: wrap;">
<div class="col-md-4 table table-bordered">
<h3 class="text-center">Table 1</h3>
<ol>
<% var i = 1; %>
<% var j = 0; %>
<% seats.forEach(function(seat){ %>
<% if(seat.player && i < perTable1){ %>
<% console.log(perTable2); %>
