suggestion to implement the Grouping, Filtering and Sorting of my table in sapui5 - sapui5

Question

I am trying to implement Grouping, Filtering and Sorting on a table with which I bring some data.
I have been able to perform Grouping and Sorting without problems, but I have not been able to filter correctly.
This would be the code of the fragment that I used for Grouping, Filtering and Sorting:
<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m">
<ViewSettingsDialog confirm="onConfirm">
<sortItems>
<ViewSettingsItem selected="true" key="Xao" text="Tipo"/>
<ViewSettingsItem key="Xoccupant" text="Ocupante"/>
</sortItems>
<groupItems>
<ViewSettingsItem key="Xao" text="Tipo"/>
</groupItems>
<filterItems>
<ViewSettingsFilterItem key="Xao" text="Tipo" multiSelect="false" items="{/d/results/Xao}">
<items>
<ViewSettingsItem key="{Xao}" text="{Xao}"/>
</items>
</ViewSettingsFilterItem>
</filterItems>
</ViewSettingsDialog>
</core:FragmentDefinition>
On the part of the controller, this would be the code it occupies:
onPress: function () {
this._Dialog = sap.ui.xmlfragment("LogonPage.LogonPage.fragments.Dialog", this);
this._Dialog.open();
},
onClose: function () {
this._Dialog.close();
},
onTableSettings: function (oEvent) {
// Abra el cuadro de diálogo Configuración de tabla
this._oDialog = sap.ui.xmlfragment("LogonPage.LogonPage.fragments.SettingsDialog", this);
this._oDialog.open();
},
onConfirm: function (oEvent) {
var oView = this.getView();
var oTable = oView.byId("table0");
var mParams = oEvent.getParameters();
var oBinding = oTable.getBinding("items");
// apply grouping
var aSorters = [];
if (mParams.groupItem) {
var sPath = mParams.groupItem.getKey();
var bDescending = mParams.groupDescending;
var vGroup = function (oContext) {
var name = oContext.getProperty("Xao");
return {
key: name,
text: name
};
};
aSorters.push(new sap.ui.model.Sorter(sPath, bDescending, vGroup));
}
// apply sorter
var sPath = mParams.sortItem.getKey();
var bDescending = mParams.sortDescending;
aSorters.push(new sap.ui.model.Sorter(sPath, bDescending));
oBinding.sort(aSorters);
// apply filters
var aFilters = [];
var sQuery = oEvent.getParameter("query");
if (sQuery) {
aFilters.push(new Filter("Xao", FilterOperator.Contains, sQuery));
}
oBinding.filter(aFilters);
},
And this is the view of my table, what I want to filter is all that contains the Xao section of my table.
<Table inset="false" items="{/d/results}" id="table0" width="auto">
<items>
<ColumnListItem type="Active" id="item1">
<cells>
<Text text="{Xao}" id="text7"/>
<Text text="{Xoccupant}" id="text8"/>
<Text text="{ path: 'Validfrom', type: 'sap.ui.model.type.Date', formatOptions:
{ source: {
pattern: 'yyyyMMdd' },
pattern: 'dd/MM/yyyy' } }" id="text9"/>
<Text text="{ path: 'Validto', type: 'sap.ui.model.type.Date', formatOptions:
{ source: {
pattern: 'yyyyMMdd' }, pattern: 'dd/MM/yyyy' } }" id="text10"/>
</cells>
</ColumnListItem>
</items>
<columns>
<Column id="column0">
<header>
<Label text="Tipo" id="label0"/>
</header>
</Column>
<Column id="column1">
<header>
<Label text="Ocupante" id="label1"/>
</header>
</Column>
<Column id="column2">
<header>
<Label text="Fecha de Apartado" id="label2"/>
</header>
</Column>
<Column id="column3">
<header>
<Label text="Fecha de Finalización" id="label3"/>
</header>
</Column>
</columns>
</Table>
And here the code of the view, where I enable Grouping, Filtering and Sorting of my table
<headerToolbar>
<Toolbar id="toolbar3">
<Title text="Puestos de Trabajo"/>
<ToolbarSpacer/>
<Button press="onTableSettings" icon="sap-icon://drop-down-list" tooltip="Settings"/>
</Toolbar>
</headerToolbar>
Any ideas or suggestions to correctly filter my table?

Check your onConfirm function in the controller - the code for the filtering looks more like code for a search field. You have to process the filters coming from the event: https://sapui5.hana.ondemand.com/#/api/sap.m.ViewSettingsDialog%23events/confirm
For you this will contain only filters for your Xao field but my recommendatio is set a breakpoint in the function and analyse the oEvent.getParameters() structure.
