Yes, because you are creating the buttons on the click event of a button. That's why the newly created buttons are unable to restore the viewstate for that.
Better you create your buttons in Page_InIt event and make them invisible to the user. On click of button you can make those created buttons visible.
Otherwise you need to restore the viewstate of the controls. In that case refer the link:

Hi,

Make sure that you are creating the button early in the page life cycle, may be in Page_Init or Page_Load. Because, the dynamically created buttons does not hold view state. that is why you have to create the controls every time on Page_Init or Page_Load. also because the event handling will occur after the page Init stage. So, create the Image button in Page_Init event also assign onclick delegate in page_Init event only. then try.

for more refer this[^]

Hope it helps.
