How to convert MobileElement to TestObject


Is there any way to convert MobileElement to TestObject?
I did experiment which convert a TestObject to MobileElement then later convert it back to testobject and perform Mobile.tap but the result is failed

WebElement el =MobileElementCommonHelper.findElement(some_object,1)
TestObject to = WebUI.convertWebElementToTestObject(el)
Mobile.tap(to, 1)

Any help will be appreciated.
