"Add New" Cannot be removed if settings are loaded after init

I am using dropdown filter boxes, which get's the options dynamically from database
so I had to load it again after init
but when I am doing it, I am getting "Add New" even that I set it to false
also while page is loading I get the "Edit" and "Delete" on screen for ~1 second

`SetNewSetting(){
this.mySettings = {
actions: {
edit: false,
delete: false,
columnTitle: '',
add: false
},`
