Leaflet layer visualization problems with ajax Error: parseResponse was not called - ajax

Question

I'm creating a Leaflet viewer where I use ajax to get a geoserver OWS to be able to customize the display style with the following function:
function GetGeoserverJson(layer,geoserverURL,geoserverLayerName,layerAtributes,layerStyle) {
defaultParameters = {
service: 'WFS',
version: '1.0.0',
request: 'GetFeature',
maxFeatures: 120000,
outputFormat: 'text/javascript'
};
parameters = L.Util.extend(defaultParameters,geoserverLayerName);
console.log(parameters)
$.ajax({
url: geoserverURL + L.Util.getParamString(parameters),
dataType: 'jsonp',
jsonpCallback: 'parseResponse',
success: function (data) {
geoJsonLayer= new L.GeoJSON(data,{pointToLayer: function (geoJsonPoint, latlng) {return
L.circleMarker(latlng);}, onEachFeature: layerAtributes, style:layerStyle})
layerName.addLayer(geoJsonLayer);
}
});
}
Layers code:
geoserverURL= 'http://urladdress/geoserver/workspace/ows'
function PresenceAttributes(feature, layer) {
// layer.bindPopup("<b>Zone:</b> <br>"+feature.properties.zone+"<br><b>Taxon:</b><br>"+feature.properties.taxon+"<br><b>Species:</b> <br><i>"+feature.properties.species+"</i>");
layer.bindPopup(
"<table class='featureInfo'><caption class='featureInfo'>Presence</caption><tbody><tr><th>source</th><th>latitude</th><th>longitude</th></tr><tr><td>"
+feature.properties.source+"</td><td>"+feature.properties.latitude+"</td><td>"+feature.properties.longitude+"</td></tr></tbody></table>"
);
}
var NISStyle= function(feature) {
// console.log(feature)
var taxon_nis=feature.properties.taxon_class;
switch (taxon_nis) {
case "Bivalvia": {return {color:"#d19211"};}
case "Gastropoda": {return {color:"#8a6fce"};}
case "Polyplacophora": {return {color:"#2fbb00"};}
}
}
var NISAttributes= function(feature, layer) {
// layer.bindPopup("<b>Zone:</b> <br>"+feature.properties.zone+"<br><b>Taxon:</b><br>"+feature.properties.taxon+"<br><b>Species:</b> <br><i>"+feature.properties.species+"</i>");
layer.bindPopup(
"<table class='featureInfo'><caption class='featureInfo'>NIS historical</caption><tbody><tr><th>latitude</th><th>longitude</th><th>country</th></th><th>Site Name</th></th><th>Class</th><th>Species</th><th>Year first record</th><th>Reference</th></tr><tr><td>"
+feature.properties.latitude+"</td><td>"+feature.properties.longitude+"</td><td>"+feature.properties.country+"</td><td>"+feature.properties.site_name+"</td><td>"+feature.properties.taxon_class+"</td><td>"+feature.properties.species+"</td><td>"+feature.properties.year_first+"</td><td>"+feature.properties.reference+"</td></tr></tbody></table>"
);
}
var ParasitesAttributes= function (feature, layer) {
// layer.bindPopup("<b>Zone:</b> <br>"+feature.properties.zone+"<br><b>Taxon:</b><br>"+feature.properties.taxon+"<br><b>Species:</b> <br><i>"+feature.properties.species+"</i>");
layer.bindPopup(
"<table class='featureInfo'><caption class='featureInfo'>Parasites</caption><tbody><tr><th>Country</th><th>Zone</th><th>Latitude</th><th>Longitude</th><th>Taxon</th><th>Species</th></tr><tr><td>"
+feature.properties.country+"</td><td>"+feature.properties.zone+"</td><td>"+feature.properties.latitude+"</td><td>"+feature.properties.longitude+"</td><td>"+feature.properties.taxon
+"</td><td>"+feature.properties.species+"</td></tr></tbody></table>"
);
}
var ParasytesStyle= function (feature){
var taxon_parasites=feature.properties.taxon_id;
switch (taxon_parasites) {
case 1: {return {color:"#4c6fb6"};} // Artropoda-
case 2: {return {color:"#fcbf7d"};} //Alveolata-
case 3: {return {color:"#3cbfbf"};} //Platelminthes-
case 4: {return {color:"#b9d989"};} //Rhizaria-
case 5: {return {color:"#ff7f00"};} //Amoebozoa
case 6: {return {color:"#de524b"};} //Bacteria-
case 7: {return {color:"#aebaca"};} // Others-
case 8: {return {color:"#f47a6a"};} //Fungi-
case 9: {return {color:"#999999"};} //ND-
// case 10: {return {color:"grey"}};
// case 11: {return {color:"white"}};
}
}
var GeoservePresence={typeName:'COCKLES:aa_cockles_presence'};
var GeoserveNIS={typeName:'COCKLES:aa_nis_historical'};
var GeoserveParasites={typeName:'COCKLES:aa_cockles_pathogens'}
var CocklesPresence= new L.markerClusterGroup();
var CocklesNISAA= new L.markerClusterGroup();
var CocklesParasites= new L.markerClusterGroup();
GetGeoserverJson(CocklesPresence,CetmarGeoserver,GeoservePresence,PresenceAttributes,{color:"#FFC000"});
GetGeoserverJson(CocklesNISAA,CetmarGeoserver,GeoserveNIS,NISAttributes,NISStyle);
GetGeoserverJson(CocklesParasites,CetmarGeoserver,GeoserveParasites,ParasitesAttributes,ParasytesStyle);
When I code only one layer it works perfectly, but if I run the function with more layers, layers represent data incorrectly (data of NIS layer are represented in parasites one, etc.) I don't really know much about ajax and I'm new to javascript and Leaflet, so I hardly can figure out what I'm doing wrong. Maybe some problem with asynchronism? Can anybody help me?
