Table – append element and set visible

Hello,
I would like to ask, How I can at the same time, add item to table and set visible in this element? I created this metkod:

this.addElement = function(){
    thisView = this;
    var dataBinding = this.context.binding.get("value").get("tableItem");
    var table = thisView.ui.get('Table1');
    
    if(dataBinding.items.length <= 0){
        table.appendElement({});
        table.appendElement({});
        var length = table.getRecordCount();
        console.log(length); //in console I have result 2 and is good
        var sumLastRow = view.ui.get('Table1/coach_view1/sum[' + length - 1 + ']');
        console.log(sumLastRow); //in console I have result 'undefined'
        sumLastRow.setVisible(false); //in console I have error" Cannot read property 'setVisible' of undefined
    }

But when I will devide this method for two methods:

this.addElement = function(){
    thisView = this;
    var dataBinding = this.context.binding.get("value").get("tableItem");
    var table = thisView.ui.get('Table1');
    
    if(dataBinding.items.length <= 0){
        table.appendElement({});
        table.appendElement({});        
    }

this.setVisible= function(){   
        var length = table.getRecordCount();
        console.log(length); 
        var sumLastRow = view.ui.get('Table1/coach_view1/sum[' + length - 1 + ']');
        console.log(sumLastRow);
        sumLastRow.setVisible(false); 
    }

And press button1, calls addElement() method and press button1, calls setVisible(), everything work. Where do I make mistake? I need to add item and set visible at the same time. Please help.

Hi Martin,

What happens when you attempt to run the code line by line from the console?

Can you run this command with page.ui instead of view.ui?

sumLastRow = page.ui.get(“Table1/coach_view1/sum[index]”);
