Changing Label Attribute of Dojox.Mobile.Heading

Question

I have a dojox.mobile site that has a common view. I would like to reuse the view for multiple "buttons" and call a function which changes the label of the view's heading depending on which button was pushed. However, when I change the innerHTML, the back button disappears. When I use the setattr function, the label doesn't change. What is the proper way to handle this?

    <div id="MainMenu" data-dojo-type="dojox.mobile.View" data-dojo-props="selected: true" style="width: 100%; height: 100%;">
        <h1 data-dojo-type="dojox.mobile.Heading">View A</h1>

        <h2 dojoType="dojox.mobile.RoundRectCategory">Select a View</h2>
        <ul data-dojo-type="dojox.mobile.RoundRectList">
            <li data-dojo-type="dojox.mobile.ListItem" data-dojo-props="rightText:'Go!', moveTo: 'generic_view_x', callback:SetupViewA">
                View A
            </li>
            <li data-dojo-type="dojox.mobile.ListItem" data-dojo-props="rightText:'Go!', moveTo: 'generic_view_x', callback:SetupViewB">
                View B
            </li>
        </ul>
    </div>

    <div id="generic_view_x" data-dojo-type="dojox.mobile.View" style="width: 100%; height: 100%;">
        <h1 id="view_x_header" data-dojo-type="dojox.mobile.Heading" data-dojo-props="back:'Main', moveTo:'MainMenu',label:'test'"></h1>

        require(["dojox/mobile/parser", "dojox/mobile", "dojox/mobile/deviceTheme", "dojox/mobile/compat", "dojo/domReady!"],
                function(parser) {
                parser.parse();
                });

With widgets, like the header, its best to use its get/set to change attributes of the widget.

you should use:

 dijit.registry.byId("view_x_header").set("label", "View B");
