You are using the same variable local!fetch to save data for both - text field (Studen ID) as well as button(Search) click. And in filters you are using ri!PorjectID. So if my understanding is correct, you need to change the value and saveInto for text Field Students ID to ri!PorjectID. If ri!PorjectID is for some another purpose, consider creating a new variable that stores student ID data and add filter logic for that variable in the queryEntity() code. 
 Hope it helps.
