I am new to SAP UI5, created SAP Fiori App using template(List Report).
I have created a custom filter in smart filter using Fragment:

<smartfilterbar:ControlConfiguration id= "SmartFilterBar" key="Customfilter" 
index="1" label="Days" visible="true" 
visibleInAdvancedArea="true" groupId="_BASIC">
<smartfilterbar:customControl>
<core:Title id= "SmartFilter" text="Days" />
<Label text="Days"/>
<Input id="Days" 
type="Text">
<core:Item text="Days" />
</Input>
</smartfilterbar:customControl>
</smartfilterbar:ControlConfiguration>

Now the requirement is to set default value of this customfilter(Days).
In controller on event onBeforeRendering, i am trying to get the smartfilter and using setfilterdata function:

onBeforeRendering: function()
 {
var oSmartFilter = this.getView().byId("SmartFilter");
var oJSONData = 
Days:
operator: "EQ",
low:"5";
oSmartFilter.setFilterData(oJSONData, true);

but when Fiori app loads it doesn't give any error nor set default value.
Any help/suggestion will be helpful.

Thanks in advance.
