How to get bean property value in JavaScript without using hidden tags in XHTML?

I pass the values to managedbean using JSON and remotecommand but when I try to see the managed bean's value in JavaScript I see the default value not the updated value.

I do not want to refresh the page or use hidden tags in XHTML as I might need much data exchange.

When the value changed: 

<script>
    var json= [ { name : 'zoom',  value : zoomLevel }  ];          
    sendParams(json);
</script>

in my .js file I use remotecommand:

function sendParams(jsonData) { 
    passToJSFManagedBean (jsonData);  
}

in .xhtml I call the function in the managedbean:

<p:remoteCommand name="passToJSFManagedBean" id="passToJSFManagedBeancmd" action="#{tagBean.setParams}" process="@this" />

in managed bean:

public void setParams() {
   this.zoom= Integer.parseInt(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("zoom")); 
   System.out.println("Zoom level: "+zoom); 
}

Then we could see the value passed managed bean. But when I try in js the zoom value is not updated and has the default value. 

alert('#{tagBean.zoom}');

Is there any way to get managed bean's properties in javascript without using hidden tags in xhtml ? Important is that the Page dose not need to refresh. Is it possible to use remotecommand to get managedbean values? Thanks for help.

In primefaces, via requestContext I can get the bean's property.
