Why not fix the bug?

Describing the Onhange bug 1. In the filed tab of form, Add a Method. And then select Onhange as Method's activation condition. 2. Even if the value of that field is changed after opening the corresponding form, the method doesn't work. For example, if a date type of the Property which Onchange occurs at is item, screen which refers to serching for item type section will be opened. After selecting an item on the serching screen, when you click the check button, the screen is closed and the keyed name of the selected item is entered in the corresponding field. in this case, the onchange method which was put in the field in the previous version of sp12 is activated, but the corresponding event does not work from sp12 version. So, i uploaded the above information to the forum a few months ago, I've heard that you had been aware of the bug and planned to fix it a later version. But the same bug occurs again in the sp14 version. Can you confim this again?
