Id value changed for UI elements in sapui5

Hello all,

I have created a SAPUI5 app and in that i have few input fields in a table. In the code i have mentioned the ID for these input fields but in the inspect element when i check these fields, the ID is appended with _clone.

For example, I have 1 input field for which i have given the ID as "description", but in inspect element the Id is displayed as "description-__clone0-inner".

My Question is why is that _clone being displayed for all the elements?

Thank you,

Navya
