UI Text isn't updating text on Button click during the gamePlay [Read description],

I have a Button prefab that i am using to dynamically create buttons using script. I also have a text field UI to show the result on that. I have a script attached to these buttons & my Goal is that when a user Clicks on the button that i created, the button.text of that button should be shown onto UI text element. All seems to be working good, except the text of the button i intend to show, isn't appearing in UI text element. When the game is in play mode & i click on some button, the UI text doesn't show button text, but instead when i stop the game it then shows the button value. Meaning that my logic isn't working during the gameplay but works only after the gameplay when game stops. Please any solution?
