How can we save selected input of select2 in elementor custom control?

I am also using select2 and ajax API for generating dynamic options. Everything works except the selected value is not previewed when we refresh the page.
I tried trigger (‘change’) but didn’t work instead, it stuck to loop and got “Maximum call stack size exceeded” error.

  onReady: function() {

        this.control_select = this.$el.find('.post-select');
        this.save_input = this.$el.find('.post-select-save-value');
        

        this.control_select.select2({
            ajax: {
                url:'https://thingproxy.freeboard.io/fetch/https://symbol-search.tradingview.com/symbol_search/?exchange=&type=&hl=true&lang=en&domain=production',
                dataType: 'json',   
                events: {
                    change: () => this.saveValue(),
                    keyup: () => this.saveValue()
                },

                data: function (params) {
                  return {
                    text: params.term, 
                  };
                },         
                processResults: function (data) {
                    //console.log(data);
                    const myObj = data;
                    let symb = [];
                    let obj = {};
                    myArray = []; // making empty array before returning new values
                    for(let x in myObj){
                        myArray.push({
                            id: x,
                            text: myObj[x].exchange+':'+myObj[x].symbol.replace(/<\/?[^>]+>/gi, ''),
                            symbol: myObj[x].exchange+'-'+myObj[x].symbol.replace(/<\/?[^>]+>/gi, '')
                        });
                    };
                    return {
                        results: myArray,
                    }
                },
              },

        });

        this.control_select.change(() => {
            this.saveValue();
        })

    },

        saveValue: function() {
            let index = this.control_select.val();
            this.setValue(myArray[index]);          
        },

        onBeforeDestroy: function() {
            this.saveValue();
        }
