On page reload, check boxes get selected and then disappear automatically within a second

I have a problem with a function that i'm writing. Basically, I'm simulating a landing page. The landing page will contain a querystring. What I'm doing is to deserialize it on a button click and show(to check) the checkboxes defined in the querystring in the HTML.

Below is the click function which contains two functions. The first one "simulateLandingPage" performs the url change. The second one called "selectFacetsAutomatically" deserializes the "landingUrl" path and checks automatically the checkboxes in the HTML page according to what is defined in the querystring.

The problem that I'm encountering is that when I click on the "reload-page" button everything works but the checkboxes get selected just for a second and then disappear automatically quickly without any reason. Hence the page won't show the selected checkboxes in the end but just this weird thing.

Can anyone help? I'm pretty new to this and i'm stuck. Thanks a lot!

$(".reload-page").click(function() {
     var landingUrl = "size:4,10,16|base_colour:1,4|brand:53,3392,12767";
     simulateLandingPage(landingUrl);
     selectFacetsAutomatically(landingUrl);
     return false;  
});

 function simulateLandingPage(landingUrl){
        window.location.href = "refinements.html?refine="+ encodeURIComponent(landingUrl);
        return false;
    }

function selectFacetsAutomatically(landingUrl){

    var facetGroup = [];
    var selectedFacets = [];
    var facetType;

        //split string when it finds the pipe symbol
    $.each(decodeURIComponent(landingUrl).split(/\|/), function (i, val) {

         selectedFacets.push(val);

         console.log("val", selectedFacets[i].split(/\:/)[1].split(/\,/));

         facetType = selectedFacets[i].split(/\:/)[0];
         facetGroup = selectedFacets[i].split(/\:/)[1].split(/\,/);

         $.each(facetGroup, function(i,val){

            var facetToBeSelected = facetType + "_" + val;
            $('[data-id='+facetType+']').find("#"+facetToBeSelected).prop('checked', true);

         });
    });

    return false;
}
