SAPUI5 IconTabBar Binding different associations

Hello together,

I created a SAPUI5 Master Detail Kapsel Application from WebIDE. I have a Icon Tab Bar with 2 fragments.

Detail.view:

	<IconTabBar select="onDetailSelect" id="idIconTabBar">
				<items>
		<IconTabFilter icon="sap-icon://hint">
	<content>
<core:Fragment fragmentName="z.release.view.DetailInfoForm" type="XML"/>
						</content>
	 </IconTabFilter>
<IconTabFilter text="Open" icon="sap-icon://accelerated" id="__filter1" modelContextChange="OnComment">
<content>
<core:Fragment fragmentName="z.release.view.DetailCommentForm" type="XML"/>
						</content>
					</IconTabFilter>
				</items>
			</IconTabBar>

If I run this application I can see both filters:

The problem is I see only on the first IconTabBar because the binding is created automatically from the template:

Detail.controller:

bindView: function (sEntityPath) {
		var oView = this.getView();
		oView.bindElement(sEntityPath);
		var frag = this.byId("detailFragment");
		frag.bindElement(sEntityPath + "/STEP_INFO");
		//Check if the data is already on the client
if (!oView.getModel().getData(sEntityPath)) {
			// Check that the entity specified actually was found.
oView.getElementBinding().attachEventOnce("dataReceived", jQuery.proxy(function () {
				var oData = oView.getModel().getData(sEntityPath);
				if (!oData) {
					this.showEmptyView();
					this.fireDetailNotFound();
				} else {
					this.fireDetailChanged(sEntityPath);
				}
			}, this));
		} else {
			this.fireDetailChanged(sEntityPath);
		}
	},

I need a binding where I can an other association like /STEP_INFO for every different IconTabFilter. How must I change the coding in the detail controller?
