Issue with angular translation in custom filter

I am trying to create a filter for showing the elapsed date and time in angular js and is working fine. Now I am trying to add translation to it but that time its showing the keys instead of the values.I think the issue is because the translation is not loaded while the filter is executing.

I am trying translation in the code like

 if(hours){
                    result+= " "+hours+$translate.instant("elapsedFull.hours");
                }
                if(minutes){
                    result+= " "+minutes+$translate.instant("elapsedFull.minutes");
                }
                if(seconds){
                    result+= " "+seconds+$translate.instant("elapsedFull.seconds");
                }
