UI5 OData Search Help not displaying values - odata

Question

this is the odata response i am getting:
my desired result would be a search help that displays the "TypRolle", "RolleNr" and "RolleOri" columns of the odata response. But right now i am stuck at trying to just display one of them, the "TypRolle" one.
this is what my search help looks like right now:
As you can see, no values are being displayed.
Here is my valueHelpRequest method:
var roletypeUrl = "my odata url";
var attModel = new sap.ui.model.json.JSONModel();
var link = this.getView().byId("roletype"); // roletype input field
var oDataModel = new sap.ui.model.odata.v2.ODataModel(roletypeUrl, {
json: true,
loadMetadataAsync: true
});
oDataModel.read("/ZshNsiAgr01xxlEinzelTypSet", {
success: function(oData, response) {
attModel.setData(oData);
var oValueHelpDialog = new sap.m.Popover({
title: "Rollentyp auswählen",
footer: [new sap.m.Button({
text: "Ok"
})]
});
oValueHelpDialog.openBy(link);
var oItemTemplate = new sap.m.StandardListItem({
title: "test",
description: "{TypRolle}"
});
var oHelpTable = new sap.m.Table({
width: "300pt",
columns: [
new sap.m.Column({
header: [
new sap.m.Label({
text: "Rollentyp"
})
]
})
],
items: {
path: "/results",
template: oItemTemplate
},
items: [
new sap.m.ColumnListItem({
cells: [
new sap.m.Text({
text: "{TypRolle}"
})
]
})
]
})
oHelpTable.setModel(attModel);
oValueHelpDialog.addContent(oHelpTable);
I am very thankful for any kind of suggestion and look forward to your answers :)

Answer 1

If you have to do it with JSON model ... here it is
]
})
]
})
oHelpTable.bindAggregation("items", "/results", new sap.m.ColumnListItem({
cells: [
new sap.m.Text({
text: "{TypRolle}"
})
]
}));
oHelpTable.setModel(attModel);
oValueHelpDialog.addContent(oHelpTable);
Or else you can directly bind to your default OData model as well and it can fetch the data automatically without you writing the read
