If I understand the question, the meaning or better to say usage of "to je ono" is slightly different. You can use it when something has been finally done (especially after long tough process of reaching the goal succesfuly). But, I think, it's not synonym to your sugestions. So the situation fits, but the meaning is different. It is commonly used as expression of happiness when you finished something, or to encourage someone to continue because he or she makes positive progress right at the time. Note: I'm not an expert, I'm just a native speaker. So I might be wrong.
