Yith Ajax GRID, LIST

Hello,how i can change the grid/list to use ajax, i saw it working in this demo: https://live.yithemes.com/bazar/shop/?max_price=100&min_price=0

if i push the buttons located beside in “VIEW AS” it order the table very fast with AJAX and idk how to activate this option in our site, if i push those buttons it reload the page without ajax here: https://somosdata.com/winespectrum/shop/, we actually use YITH WooCommerce Ajax Product Filter Premium 3.0.10
