Dataset - SetFilter

hello there,

i have tried the same but did not work

$w("#dataset1").setFilter(wixData.filter()
                                            .eq('avaliability',true)
                                            .contains('propertyCat','Rent')
                                            .contains('propertyType',''));

avaliability is a boolean field
also
.contains(‘propertyCat’,‘Rent’) is not working !?
