GWT-Bootstrap Modal not shown after setVisible is called - gwt

Question

I have a simple modal that I want to show when a button is clicked.
Here's the Code that I'm using to show the Modal
#UiHandler("submit")
void handleClick(ClickEvent e){
ModalDialogDemo modalDialog = (ModalDialogDemo) RootPanel.get().getWidget(2);
modalDialog.setHeight("200px");
modalDialog.setWidth("100px");
modalDialog.setVisible(true);
if(modalDialog.isVisible()){
System.out.println("Successfully Displayed the Modal!");
}
else{
System.out.println("Something went wrong.");
}
}
Even though the Modal isn't displayed on the screen the Message logged onto the console is the former i.e. Successfully Displayed the Modal!
I did some digging with firebug and before the button is clicked the rendered HTML is
<div>
<div class="modal" style="display: none;" aria-hidden="true">
<div class="modal-header"><a class="close" data-dismiss="modal">×</a><h3>Name</h3></div>
<div class="modal-body"><div class="gwt-Label">Modal Content Comes Here</div></div>
<div class="modal-footer"><div class="gwt-Label">And this is the footer</div></div></div>
</div>
after the button is clicked it changes to
<div style="height: 200px; width: 100px;" aria-hidden="false">
<div class="modal" style="display: none;" aria-hidden="true">
<div class="modal-header"><a class="close" data-dismiss="modal">×</a><h3>Name</h3></div>
<div class="modal-body"><div class="gwt-Label">Modal Content Comes Here</div></div>
<div class="modal-footer"><div class="gwt-Label">And this is the footer</div></div></div>
</div>
The first div has the height and width that I set applied and the aria-hidden also cleared but the child div which actually contains the modal isn't affected.
I don't know how I can tell GWT to apply the changes to the child div also, can someone help me out with this?
Edit:
This is my ModalDialogDemo.ui.xml
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui"
xmlns:b = "urn:import:com.github.gwtbootstrap.client.ui">
<g:HTMLPanel>
<b:Modal title="VipName" backdrop="STATIC">
<g:Label>Modal Content Comes Here</g:Label>
<b:ModalFooter>
<g:Label>And this is the footer</g:Label>
</b:ModalFooter>
</b:Modal>
</g:HTMLPanel>
</ui:UiBinder>

You need to call the show() method on a GWT-Bootstrap modal object to display it.
Updated:
In ui.xml file, Assign one id for modal.
<b:Modal title="VipName" ui:field="vipNameModel" backdrop="STATIC">
In ModalDialogDemo.JAVA file, Get that object.
#UiField
Modal vipNameModel;
Create getter method:
Modal getVipNameModel()
{
return vipNameModel'
}
then call, modalDialog.getVipNameModel().show(); from ModalDialogDemo class
