Avatar upload in form, when click reset button, the preview image is hidden

[anhchungite]

Everything is wonderful until I click reset button.
My code html:

<form class="form-validate form-horizontal" id="user_form" method="post" enctype="multipart/form-data">    
    <div class="kv-avatar center-block text-center" style="width:200px">
           <input id="avatar-1" name="hinhanh" type="file" class="file-loading">
    <div class="help-block"><small>Allow size < 1000 KB</small></div>
    <input type="submit" class="form-control">
    <input type="reset" class="form-control">
</form>

and javascript config code:

$("#avatar-1").fileinput({
    overwriteInitial: true,
    maxFileSize: 1500,
    showClose: false,
    showCaption: false,
    showBrowse: false,
    browseOnZoneClick: true,
    removeLabel: '',
    removeIcon: '<i class="glyphicon glyphicon-remove"></i>',
    removeTitle: 'Cancel or reset changes',
    elErrorContainer: '#kv-avatar-errors-2',
    msgErrorClass: 'alert alert-block alert-danger',
    defaultPreviewContent: '<img src="/uploads/default_avatar_male.jpg" alt="Your Avatar" style="width:160px"><h6 class="text-muted">Click to select</h6>',
    layoutTemplates: {main2: '{preview} {remove} {browse}'},
    allowedFileExtensions: ["jpg", "png", "gif"]
});
