"I want to focus this button after I click that"
If "this" is the button above, what is "that"?

sorry for my bad english, now I did correction,thank you.

Oh, ok.
Usually when you click a button, it will keep focus unless either you change the focus or the page reloads. Is the page reloading?

In wider sense of the word "click" (usually used in terminology related to "click event handling"), this is not exactly so. You can use the "accelerator" key, then the button won't be focused. The whole idea to enforce focus is bad.
Anyway, I answered the question, please see.

still confusing on which button click?

<cc1:customimagebutton id="SoDtilButton"> this one~

yes, page is reloading. But I don't know why page is reloading.
Actually, when I click the button, a form will be appear, then I close that form ,finally the button is in focus.

Please see my comment to the question, in response to the comment by Andy Lanng, as well as his comment itself. Here is the whole thing: your button will be focused in most cases. But if it won't, it means that the user does not want to focus it. You just should not do anything about it. It's really bad to enforce focus without a purpose.
However, you can always use JavaScript focus method: https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/focus[^].
