Input values are not updated in managed bean

The field values of my HTML page are not sent to my managed bean. By invoking the action, the values are null. My html code is:

<form jsf:id="form">
    <fieldset>
        <label> <span
                class="block input-icon input-icon-right"> <input
                    type="text" class="span12" placeholder="Usuário"
                    jsf:id="usr" jsf:value="#{loginBean.user}" />
                    <i class="icon-user"></i>
            </span>
        </label> <label> <span
                class="block input-icon input-icon-right"> <input
                    type="password" class="span12" placeholder="Senha"
                    jsf:id="pwd" jsf:value="#{loginBean.password}" />
                    <i class="icon-lock"></i>
            </span>
        </label>

        <div class="space"></div>

        <div class="clearfix">
            <button jsf:action="#{loginBean.doLogin()}" jsf:id="btn"
                    class="width-35 pull-right btn btn-small btn-primary">
                <i class="icon-key"></i> Login
            </button>
        </div>

        <div class="space-4"></div>
    </fieldset>
</form>

I was put and syout on my LoginBean.doAction method and it print null for user and password attributes.

Am I doing something wrong?

As per the comments, you declared the XML namespace xmlns:jsf on URI http://java.sun.com/jsf, based on the old java.sun.com host.

This has a bug in older Mojarra versions. New JSF 2.2 specific features such as <f:viewAction> and "HTML5 friendly markup" weren't initially available on XML namespace with the old java.sun.com host in the URI, but only on xmlns.jcp.org host. This was fixed in Mojarra 2.2.1-2.2.2.

As you're on Java EE 7, you should really abandon java.sun.com host in XML namespace URIs and use xmlns.jcp.org instead. 

<html ... xmlns:jsf="http://xmlns.jcp.org/jsf">

That said, that this bug occurs also indicates that you're using a rather old Mojarra version. It's wise to upgrade it. It's currently already at 2.2.9 (which in turn has the awkward bug that line numbers aren't included in class files, so you couldn't step through the source in IDE's debugger, you'd better pick 2.2.8 if this is mandatory; this will be fixed in 2.1.10).
