[Plugin: Events Manager] Allow Search Events – Date Picker not loading UI_CSS

When enabling the search option,
I enable the date picker.
The date picker works
However it is not loading the css file for it

'ui_css' => plugins_url('includes/css/jquery-ui-1.8.13.custom.css', __FILE__),

This is the function which calls ui_css
It works in the admin. It works in the Submit an Event.
But it does not work when enabling search

if( load_ui_css || $("#em-date-start-loc, #em-date-end-loc").length > 0 ){
            //alert('worked because values filled in');
		$('ui-datepicker-div').css();
		var script = document.createElement("link");
		script.rel = "stylesheet";
		script.href = EM.ui_css;
		document.body.appendChild(script);
	}
