How can I change the center point and zoom factor of the "navbar"? - leaflet

Question

When changing map layer (addoverlay) I change the setView, however, the Home button of the "navbar" does not change with it. If I press it on a different map layer than the first (default overlay), the value of the first map layer is used when using the home button.
First (default) overlay = "ReizenL".
var map = L.map('map', {
messagebox: true,
fullscreenControl: true,
layers: [Esri_NatGeo, ReizenL],
minZoom: 3,
maxZoom: 20,
center: [<?php printf($XcoorL) ?>,<?php printf($YcoorL) ?>],
zoom: 3,
});
Navbar code:
var navbar = L.control.navbar({
center: [<?php printf($XcoorL) ?>,<?php printf($YcoorL) ?>],
zoom: 3,
}).addTo(map);
Addoverlay code:
map.on('overlayadd', function(e) {
// alert(e.layer._leaflet_id);
switch (e.layer._leaflet_id){
case 181:
map.setView([<?php printf($XcoorL) ?>,<?php printf($YcoorL) ?>], 3);
break;
case 196:
// map.setView([48.01932, 5.36133], 5);
map.setView([<?php printf($XcoorS) ?>,<?php printf($YcoorS) ?>], 5);
break;
case 197:
//map.setView([52.30512, 4.77081], 9);
map.setView([<?php printf($XcoorH) ?>,<?php printf($YcoorH) ?>], 9);
break;
case 198:
//map.setView([50.80593, 4.68567], 8);
map.setView([<?php printf($XcoorW) ?>,<?php printf($YcoorW) ?>], 8);
break;
}
});
I change the code for map.setView while de Leaflet_id is not trustworthy:
map.on('overlayadd', function(e) {
// alert(e.name);
switch (e.name){
case "<?php printf($legend02) ?>":
map.setView([<?php printf($XcoorL) ?>,<?php printf($YcoorL) ?>], 3);
break;
case "<?php printf($legend03) ?>":
// map.setView([48.01932, 5.36133], 5);
map.setView([<?php printf($XcoorS) ?>,<?php printf($YcoorS) ?>], 5);
break;
case "<?php printf($legend04) ?>":
//map.setView([52.30512, 4.77081], 9);
map.setView([<?php printf($XcoorH) ?>,<?php printf($YcoorH) ?>], 9);
break;
case "<?php printf($legend05) ?>":
//map.setView([50.80593, 4.68567], 8);
map.setView([<?php printf($XcoorW) ?>,<?php printf($YcoorW) ?>], 8);
break;
}
});
Every time I click on a map layer and the value "e" is requested in the function: "map.on('overlayadd', function(e) {" the coordinates are adjusted with "map.setView" in addition the coordinates must also be and the zoom factor in "L.control.navbar" can be adjusted.
I used php while the names are different in the possible three languages.
