Memory leak on refreshing page

Hi,

I'm developing application using SAPUI5 and I find problem with memory leakage after refreshing page. When page is loaded first time it consume ~50 mb of memory, but with each refreshing amount of assigned memory is getting bigger by 20-30 mb.

My guess is that when I create in view files layout, it is generated every single time but never released. Is there any way I can make site using controls already created or should I delete them before page loading or after page leaving?

Thanks,

Ireneusz
