Entity list - Search function happening before JavaScript

Hello, 

I have created an entity list and page template for my Dynamics Portal, this entity list also uses the search function. I am attempting to search for a full name with just the surname. This is returning a result of 0 contacts. I have attempted to resolve this by adding some JavaScript to add the '*' wildcard.

This method only works on the second attempt due to the search function happening before the javascript adds the wildcard to the search.

Is there a way to delay the search or start the JavaScript first?

Thank you,

Joe.
