search help translation of field name

I have craeted custom search help with field 1 and field 2.

I have created structure related to search help with two custom data elements and also maintained their translation in Spanish language .

When I am calling the module program with logon language as english ,search help field name are visible in english but when I am calling the same program as logon language as Spanish then no Spainsh translation coming for newly created custom data elements , they are visible in English language only .

How to translate the data element while calling search help?

Already maintained custom data elements in both the language.

This is happening with custom data elements only, standard data elements are translating automatically while changing the logon language.

Can anybody help me out with this?
