Change the visibility of delete icon in the detail based on the result of call back function

Hello Community, 

I wanted to change the visibility of delete icon in the editable detail based on the result of callback function . 

I have tried calling the callback function in init and set the result to a variable 

and then called this.callParent(arguments); to trigger getDeleteRecordMenuItem() function. In getDeleteRecordMenuItem() based on the result in variable, the code is written to show/hide the delete button.

Now the result is intermittently working due to sync issues.

Any suggestions on how to achieve this is really helpful.
