Values not appearing to filter category in fragment

Hello,

I'm trying to add values in filter category but it is coming blank.

see below XML view snippet.

<ViewSettingsFilterItem id="Library"   key="LIB" text="Library Prefix" multiSelect="true"><items ><ViewSettingsItem key="{/Prefix}" text="{/Library}" /></items></ViewSettingsFilterItem>

JavaScript Controller Snippet

this._oDialog = sap.ui.xmlfragment("com.view.SettingsDialog", this);

this.getView().addDependent(this._oDialog);

var url = "/sap/opu/odata/sap/ZXX_SRV";

var oModelDetail = new sap.ui.model.odata.ODataModel(url, true);

var singleRowModel = new sap.ui.model.json.JSONModel();

oModelDetail.read("/LIbrarySet", null, null, false,

function(oData, oResponse) {

singleRowModel.setData(oData);

MessageToast.show("Read Lib sucess");

},

function(oError) {

MessageToast.show("Read failed");

}

);

this._oDialog.setModel(singleRowModel);

}

Can you please help me.

Thanks!
