In the above code if I click the change button data should be updated but empty data is showing in accordion. Kindly let me know how to resolve this issue.

you should use track by to Understand angular that data is changed.

*ngFor = "let item of data1;trackBy:identify"

identify(index,item){
  return this.count;
 }
