hashAdjustment JS not triggering reload of taggedContent.List response

I'm working on a custom widget that uses tagedContent.List to search on a tag and display the results in a Pager. Here are the basics:

setquery.vm

#registerEndOfPageHtml()
<script type="text/javascript">
jQuery(function(j){
j('#$core_v2_widget.WrapperElementId #custom-search-btn').on('click',function(e){
e.preventDefault();
console.log('here');

var tagSearchStr = '';

var select = j('#$core_v2_widget.WrapperElementId .custom-search-tag-select');
var keyword = j('#$core_v2_widget.WrapperElementId .custom-search-keyword');
if(select.val() !== '0') {
//keyword.val('');
tagSearchStr = select.val()
}
else if(keyword.val() !== '') {
tagSearchStr = keyword.val();
}

if(tagSearchStr !== '') {
console.log('searching: ' + tagSearchStr);
var hashAdjustment = {};
hashAdjustment['Tags'] = tagSearchStr;
j.telligent.evolution.url.hashData(hashAdjustment, {
overrideCurrent: true,
prefix: '$core_v2_encoding.JavascriptEncode($core_v2_ui.PageIndexQueryStringKey)'
});
}
})
})
</script>
#end

#set ($query = "%{Tags='test',PageSize=$pageSize,PageIndex=$pageIndex,ApplicationTypeIds=$applicationTypeId}")

list.vm

$core_v2_widget.ExecuteFile('setquery.vm')

#set ($response = $core_v2_taggedContent.List($query))

#foreach($item in $response)
<div class="xs-text-6">$item.Content.HtmlName("web")</div>
#end

## Paging
#set ($pagerOptions = "%{ PagedContentFile = 'list.vm', LoadingIndicator = 'true', LoadOnAnyHashChange = 'true' }")
$core_v2_ui.Pager($response.PageIndex, $response.pageSize, $response.TotalCount, $pagerOptions)

The initial page load works great (I'm getting expected results for that default tag "test"). I have an option to change the tag it's searching on and when that's triggered in the JS in the setquery.vm file, the result box flashes like it's reloading things (and I get the hash added to the url), but the results don't actually change. What am I missing?
