"use strict";
var PageController = Controller.extend("pro.controller.Page", {
onInit: function() {
// set explored app's demo model on this sample
var oModel = new JSONModel(jQuery.sap.getModulePath("pro", "/model/model.json"));

Answer 1

add a 'key' attribute to the combobox item. Also give the combobox and teaxarea some IDs.
<ComboBox id="selectBox" items="{ path: '/ProductCollection', sorter: { path: 'Name' } }">
<core:Item key="{Naame}" text="{Name}" /> </ComboBox>
<TextArea id="textArea" value="" rows="8" />
On click of submit, get the selected values from the combobox and text area and push them into the model. I assume that you wanted to push this new data to the existing model and also your existing model is an array of objects.
sap.ui.define([
'jquery.sap.global',
'sap/ui/core/mvc/Controller',
'sap/ui/model/json/JSONModel'
],function(jQuery, Controller, JSONModel) {
"use strict";
var PageController = Controller.extend("pro.controller.Page", {
onInit: function() {
var oModel = new JSONModel(jQuery.sap.getModulePath("pro", "/model/model.json"));
this.getView().setModel(oModel);
},
onPress: function() {
//get the value of the selected item in the combobox
var selectedVal = this.getView().byId("selectBox").getSelectedKey();
//get the textarea value
var textAreaVal = this.getView().byId("textArea").getValue();
this.getView().getModel().oData.push({
key: selectedVal,
value: textAreaVal
});
}
});
return PageController;
});
