Table not updating when list source changing

Hi,

I've some problems with the table. In fact i've 3 columns but to update each value, I need a select object of 400 lines. The problem is i've something like 200 lines in the table so it isn't fluent anymore ... So i used a control panel to add and modify datas in the table. The problem is the table isn't actualizing in real time: when i use the pagination or search system i find the datas (so they are correctly added), but the list isn't actualizing by itself. Do you know how I can do to fix this ?

Here is a screenshot
