Hi Ogulcan,
That's pretty huge application! 
I have made few changes to the code, now both page title and table model are working fine. Check the sample here: Plunker
I have done changes in promdepo.view.js file and mddepgeliade.view.js.
In promdepo.view.js, on press event of 201 and 202 buttons, I am setting the title property - Line #35 and #48
In mddepgeliade.view.js, I have used a named model in order to get rid of confusion. Line#984 and Line#985
I also commented Line#993 code, that is not required now.
Regards,
Sai Vellanki.
